How to drill metal with a drill - detailed step-by-step instructions

You've almost drilled to the required depth and you can't go any further.

Almost - this means, for example, for a depth of 5 cm you underdrilled 5 mm.
Then you hit something. There are rare cases when you come up against something major, for example, some hard monolithic cobblestone that cannot really be drilled out or crushed in any way. If the self-tapping screw on which you are going to hang the structure does not have strict load requirements, then try taking the same self-tapping screw, but 5 mm shorter, and simply cut the dowel, which is not fully inserted into the hole and sticks out with a small end, with a construction knife. as shown in the picture:

Next, just take a self-tapping screw that is 5 mm shorter and screw it into the trimmed dowel. This is not a very good practice, but sometimes there are situations when nothing else can be done and then this is the way out!

Tools

To drill a reinforced concrete surface, you need to use specialized tools - in this case, you won’t be able to get by with a homemade tool.

Depending on your preferences and the diameter of the hole, you can use a hammer drill or a small electric hammer drill. The first option has less power, but at the same time has less weight and a convenient design. The hammer drill, accordingly, has greater potential, weight and dimensions.

In addition to the existing tool, it is necessary to purchase special drill bits that allow you to work with a concrete surface. For a hammer drill, drills with a Pobedit tip are selected.

The hammer drill has its own set of impact attachments, which, in most cases, are quite sufficient. As additional components for a hammer drill, you can also use drills with a tip.

Concrete drills

To form holes with a diameter of 35 to 120 mm, crown bits are used, which have Victory teeth - with their help, grooves for sockets, switches, etc. are drilled. If you are wondering whether it is possible to drill concrete with a screwdriver, then there are also tungsten carbide coated bits for this purpose. However, it should be noted that they are only suitable for units with a power of at least 1 kW.

Preparation

Before drilling into concrete, you need to prepare the available tools. First of all, the fixing cartridge is inspected for the presence of sand or other foreign elements - if any, they must be removed. For this purpose, you can use a clean, dry rag;

Hammer head

• The drill should fit into the groove freely so that you can feel that it has gone in all the way. This is a mandatory condition, failure to comply with which may render the tip unusable. If we are talking about a hammer drill, then the drill must be clamped as tightly as possible; in hammer drills, the clamping is carried out automatically;
• Before drilling into a concrete ceiling, you must protect your face with a respirator or plastic visor. When working with walls, the use of personal protective equipment is also desirable, although not so critical;

Drilling

The process of drilling concrete is not particularly complicated and consists only of the ability to work with the tool. When working with drills, you should combine the hammer mode with drilling.

If you use crown attachments, the impact mode must be turned off. The only possible problem during this process will be the reinforcement frame reinforcement that may get in the way of the drill.

Drilling concrete

Before drilling reinforcement in concrete, you need to change the tip for working with concrete to a regular metal drill and drill through the obstacle

It is important to remember to turn off the bumper mode before drilling reinforcement in concrete

In addition to the above, there are also a number of useful tips that will help you achieve quality results.

• Non-professional construction tools are not designed for long-term loads, which should be taken into account when working with them. The case must not be allowed to overheat - on average, the period of continuous operation of the equipment is no more than 15 minutes, after which the mechanism requires cooling. These 15 minutes of inactivity will be quite enough;
• When drilling, the drill becomes very hot and when a critical temperature is reached, the pobedit tip begins to deform. To cool the drill, simply immerse the tip in water - the more often you perform this operation, the less the consumables will wear out;

Concrete drill

If the drill is stuck, in no case should you try to turn it by increasing the speed - at best, you will break the drill, and at worst, you will render the tool itself unusable. It is necessary to remove the tip from the socket, charge a similar one and drill a hole next to it - only after this you can try to “rescue” the drill from captivity;

Diamond drilling

If you are thinking about how to drill through a concrete slab or create a large-diameter hole, then you cannot do it on your own. The most effective is diamond drilling of holes in concrete and cutting reinforced concrete with diamond wheels, which are carried out using specialized professional equipment.

Diamond drilling

The cost of installations is quite high, and purchasing them for single use is irrational. It would be wiser to invite specialists who provide their services at a very reasonable price.

Tips for work

How to drill a concrete wall using special drills? Everything is quite simple. By following these recommendations, you can easily make a smooth hole in a solid wall using a drill or hammer drill.

1. Preparation. Before you start, make sure you have drills for different purposes at your disposal. A situation is possible when, when drilling a concrete wall, a master stumbles upon a metal frame. In this case, you need to change the “consumables” for concrete to a drill for metal, make a small hole in the metal frame and then continue what you started.
2. Break. When working with a hammer drill or drill, you need to take short breaks so that the drill can cool down. 15-20 seconds of continuous rotation greatly heats up the drill, which greatly reduces its strength. The important point is that cooling should be done naturally, i.e. without the use of water or other cooling elements.
3. Operating modes. If you are going to drill into a concrete wall with a drill, you need to activate a special impact mode. This can be done by turning the corresponding lever on the device body.
4. Drilling ceramics. Concrete drills are often used for drilling ceramics. To prevent the material from splitting, it is necessary to perform the work not with a hammer drill, but with a special drill with the impact mode turned off.

To ensure that when pouring concrete there are no bubbles that negatively affect the characteristics of the material, a special device is used - a concrete vibrator.

Vibrators for concrete compaction

Is it possible to cut through reinforcement in concrete with a chisel?

An outdated way to remove reinforcement when drilling a hole in concrete is to use a chisel or core. This method involves cutting a metal wire. To do this, you will need to drill a large diameter hole to provide easy access to the fittings. After this, using a sharp chisel and a hammer you will need to cut the metal wire.

You can increase the size of the hole for free access to the reinforcement using a chisel on a hammer drill. If you have enough free space to work with a metal blade, you should definitely use this method. Sawing reinforcement with a metal blade requires a lot of time and effort, but this is quite feasible if you first make a through hole.

This is interesting! If you use a chisel or blade for metal, you should use tools made of high-speed and high-strength steel.

You can go to a large hardware store and explain what you are going to drill. They will advise you on what kind of dowel and drill you need. It’s better to take a few dowels and a set of checked ones; it will still be useful on the farm. For hanging planters, I used a dowel with a hook. Drilling in a horizontal position is very difficult, so it’s better to ask your husband.

It's cool here. Weselova, drill a brick, you say? Have you purchased a PERFORATOR or at least an IMPACT DRILL? Creating a hole in wood, plastic, metal is done by CUTTING. The sharp edge of the drill precisely cuts off the layer of material. And a completely different principle when creating a hole in concrete or brick. A pobedite drill is not so much a drill as a chisel that crumbles the material, and then, due to rotation, these crumbs are removed from the hole along the auger. And you can twist a Pobedit drill bit into a brick - there will be no hole. It is necessary to hammer.

Kroky, usually a core is used to mark future holes in metal, this won’t really help a brick wall (the hammer will mark itself due to the first blows with light pressure, the main thing is a steady hand and a heavier hammer), but the core can get worse (if it’s under-heated, it will immediately become dull, if it’s overheated, it will become dull). will chip, the core is intended for plastic materials. Try putting a mark with a core on titanium or, even better, on a bearing ball.)

Yes, it seems, core punching is done so that the drill does not creep to the side when starting to drill hard material (metal), because the tip of the drill is not a needle, but when drilling chipboard, MDF and plastic, the slightest pressure - the drill penetrates into the material, and the process begins.

Somehow the thought never even occurred to me that I needed to core chipboard, MDF and plastic.

Tool preparation

To begin, select suitable drills that will be used in your work. For example, to drill a reinforced concrete wall, you need to purchase 2 types: for concrete and for metal. Any specialized store knows what they drill into walls of this type, so feel free to contact a consultant and he will help you choose the right products.

Concrete can be different, and how easy it will be to work depends on its “age”. To increase reliability, we recommend using high-quality drills. For impact drills, appropriate consumables with carbide tips are used. They easily drill through hardened concrete, promptly clearing the hole of accumulated crumbs.

To select a drill, use the following parameters:

• working part length;
• diameter;
• marking.

Scheme for drilling a concrete wall
Carefully calculate the depth of the holes in the wall and their diameter, because the final result will depend on this. For example, SDS hammer drills are used for holes up to 15 mm in diameter, and punch drills for 20 mm or more. Make sure that the spiral grooves of the product are greater than or equal to the length of the intended hole. This point is important, since too great a immersion depth makes it impossible for the tool to remove accumulated concrete chips. If all the conditions are met, the question is: “what is the best way to drill concrete walls and what kind of drill to choose?” - will disappear by itself.

Before you begin, make the final settings. An important parameter is the drilling depth. For paintings and light shelves, 25 mm is sufficient; installation of heavy hanging objects requires deeper holes. Most modern tools have the ability to adjust this indicator or a special limiter.

Execution technology

We have dealt with the need and the difficulties that arise, now we will look at how to properly drill a concrete wall.

Tool selection

First of all, let's decide what to drill into a concrete wall. Drills for wood and concrete, of course, are not suitable.

You can choose from the following options:

Drills tipped from Pobedit. But it should be borne in mind that in addition to rotation, a shock function will also be required.

But the question of how to drill into a concrete wall is not limited to the choice of consumables.

You also need to decide on the tool:

• Regular drill. Only if you don’t have anything more suitable and you only need to make 2-3 holes. And in this case, from time to time you will have to pierce the concrete layer with a steel pin with your own hands.
• Drill with impact function. It will cope with a small amount of work even if the diameter of the required holes does not exceed 13 mm. The fact is that the impact in such a device is carried out due to a metal “ratchet”, which wears out quite quickly under intense load.

Impact electric drill

Hammer. It can handle large volumes and can even use special nozzles in the form of crowns, which are ideal for drilling nests for sockets. In it, the impact is carried out due to the piston system, which is much more powerful and less likely to fail than the “ratchet” of a drill.

Hammer with "crown"

The following generalized table will help to summarize and give a final answer to the question of what is the best way to drill concrete walls:

Carrying out work

Now let's figure out how to drill a concrete wall. To do this, let's take a hammer drill as a clear winner of impromptu competitions.

The instructions for its operation are as follows:

1. We check the shaft shaft for debris. If we find one, we delete it.
2. Insert the drill until it clicks. In this case, in some models it may be necessary to pull the slider part of the “nose” of the tool towards you.
3. We bring the hammer drill to the concrete surface strictly perpendicularly and begin to drill, lightly pressing on it.

Drilling a concrete wall with a hammer drill

1. During the drilling process, the drill may get stuck. In this case, you should not try to loosen it in order to pull it out, as you may break off the tip. Simply remove the tool from the device, insert a drill of a smaller diameter and try to use it to widen the hole and free the captive product.
2. Monitor the equipment while allowing it to cool.

Is it possible to drill metal with a hammer drill? — Metals, equipment, instructions

A rotary hammer is a screwdriver, drill, jackhammer and construction mixer in one tool. How to use a hammer drill in different modes, what materials can it work with, and how to properly care for this tool?

A hammer drill is a versatile electric tool that can perform many tasks. With its help, you can drill holes in hard surfaces, tap walls, and also work in chipper mode.

At the same time, the safety of the work carried out corresponds to a high level, and even a person far from the construction industry can learn how to use a hammer drill.

From this article you will learn how to drill various materials with a hammer drill, prepare it for work, and also care for it.

What materials is the hammer used for?

Can a hammer drill drill into wood, metal or tile? Is this tool used as a concrete mixer? Many people have similar questions before buying a hammer drill. After all, you want to get the most out of an impact drill. Therefore, below are all the functions of the rotary hammer with brief explanations for each of them.

Rotary hammer functions

Drilling tiles. The drilling site is marked, and a hole is drilled at low speeds using a special drill for tiles without impact mode. Having reached the wall, the drill changes.

Drilling wood. In drilling mode without impact, at maximum speed, when using wood drills.

Drilling metal. Not recommended. It is possible to drill only thin sheet steel using special metal drills.

Stir the solution. Not recommended. You can burn out the engine due to too much load. Used only for mixing small quantities of solution with low viscosity.

Tighten screws and self-tapping screws. Not recommended. Firstly, it is extremely inconvenient due to the significant dimensions of the hammer drill. Secondly, due to the high power of the tool, there is a high risk of overtightening.

Thus, you can perform many operations with a hammer drill, but this will not always be advisable. Still, the main purpose of this tool is drilling and chiselling concrete surfaces. Therefore, it will last as long as possible when used as intended.

Preparing the hammer drill for work

Depending on the purpose for which the hammer drill will be used, the procedure for preparing it may differ. However, in most cases, before using a jack drill, you should perform the following steps:

• Study the tool and its instructions in order to comply with safety precautions and operating rules;
• Select a drill according to the type of surface, as well as the depth of the hole;
• Insert the drill into the chuck;
• Adjust the drilling depth. If a hole is required not through, but of a certain depth, you should install a limiter - it will not allow the drill to go beyond the mark;
• Plug in the hammer drill, select the required drilling mode and get to work.

Rotary hammer operating modes

Each rotary hammer has three operating modes: drilling, hammer drilling and impact mode. Depending on what material is being worked with, one or another mode is selected.

The drilling mode is used to make holes in hard materials - tiles, wood, plastic, metal, etc. The hammer drill in this mode performs the function of an ordinary drill. To activate it, switch the toggle switch to the position opposite the drill icon.

Drilling with a hammer drill

How to drill metal with a hammer drill? Select a drill of the required diameter for metal. If the diameter of the hole or the thickness of the metal is too large, it makes sense to start with small drills, gradually widening the hole formed. Hammer in drilling mode. The surface must be marked so that the drill does not “walk.” Let's get to work, controlling the heating of the motor.

How to drill tiles with a hammer drill? This operation is also performed in drilling mode. Use special drills for glass and ceramic tiles with a tungsten carbide tip or pobedit drills.

The location of the hole is marked, adhesive tape is placed on top (so that the drill does not move), or the drilling points are marked. When the tile is drilled through, the drill and mode are changed to hammer drilling (in the case of a concrete wall).

The drilling mode with impact on the switching switch is indicated by the image of a drill and a hammer. It is used for drilling holes in fragile materials - concrete, plaster, brick, etc. In this mode, the drill simultaneously rotates and strikes, due to which the material is destroyed, and dust and fragments are thrown out.

The impact mode is turned on to perform chipping, chiseling and gating. On the toggle switch this mode is indicated in the form of a hammer. Depending on the functions performed and the characteristics of the material, various attachments can be used: blades, peaks, chisels, etc. In this mode, the tool does not rotate, only chiseling.

Many modern rotary hammers also have a reverse mode. It will be very useful if the drill gets stuck. When this mode is turned on, the motor rotates in the opposite direction.

Tips for using rotary hammers

Below are a few tips that will allow you to use your hammer drill more productively and safely:

• In the mode of chiselling and drilling with chiselling, you should not press hard on the body of the tool - this will only lead to overheating of the engine and waste of energy, but will not speed up the work process.
• Accurate selection of equipment for each type of work is the key to successful and quick completion of the assigned tasks.
• When working locally with a rotary hammer, you can avoid lengthy cleaning of the room if you hold the hose of a running vacuum cleaner under the place of drilling or chiselling. If it is necessary to screw screws into a concrete surface, metal anchors are inserted into the drilled hole. If the loads are expected to be insignificant, you can limit yourself to plastic dowels.
• Use water to cool drills and remove dust only after familiarizing yourself with the composition of the drill. The fact is that some carbide drills can break when cooled with water.
• To drill large-diameter holes, use special diamond core bits instead of a drill - this will reduce labor costs and save time.

Tips for caring for a rotary hammer

In order for the hammer drill to serve for a long time and without breakdowns, it is necessary to follow a number of recommendations for its care and storage. For each model of impact drill there is an instruction manual that describes in detail the rules of use and care. However, for all rotary hammers, a number of rules can be drawn up that must be followed in any case.

The instrument should be stored in a dry, ventilated area, either in a case or without it. Before work, check the integrity of the wire insulation, as well as the body of the hammer itself. It is recommended to periodically lubricate the rotating parts of the tool, as well as completely replace the lubricant with a new one if its lubricating properties deteriorate.

Considering the fact that the cooling of the electric motor occurs due to the flow of air into the holes on the body of the hammer drill, it is necessary to ensure an unhindered supply of air flow. This means that the tool must be clean, without clogged cracks, and during operation it is forbidden to cover the holes with your hand.

If the hammer drill fails, you should contact professional technicians without trying to fix the problem yourself. Make sure that only original spare parts are used during repairs.

When can you work with a hammer drill?

Carrying out repair work using a hammer drill in an apartment building is inextricably linked to causing inconvenience to neighbors. To avoid conflict situations or even fines, you need to know your rights and responsibilities.

In accordance with the rules for the use of residential premises, it is prohibited to create noise and vibration during the period from 23:00 to 7:00.

This means that at this time, not only can you not work with a puncher, but you can’t even talk loudly, sing or play musical instruments.

Working with a hammer drill during the reconstruction or redevelopment of premises in apartment buildings is prohibited on weekends and holidays, because this action results in noise and/or vibration. It is also not allowed to perform such work on weekdays between 9:00 and 19:00.

Which hammer drill should you choose?

Drilling holes in concrete floors is difficult, since they have increased strength and often have a heterogeneous structure, including crushed stone, metal reinforcement and other fillers. A hammer drill helps to cope with this task.

, it can perform both impact and non-impact drilling. Therefore, when you have to carry out construction work such as installing plumbing, air conditioning, removing old finishes, laying electrical wiring, you cannot do without this tool. This device is multifunctional and is designed for drilling wide and deep holes.

Before you start drilling concrete, you need to choose the right hammer drill

, since it is available in several types, each of which is characterized by its own technical capabilities.

Nowadays you can find simple household and advanced professional hammer drill models on sale. Household ones are usually used for drilling holes in houses and apartments; they have a power of up to 900 W and are equipped with an SDS-plus chuck. Devices of this type are represented by the brands Black Deker, Bosch, Hundai, Skil, Enkor and Caliber. As for professional models, they are suitable for all socket boxes, have additional protection against vibrations and can work for a long time without interruption. Professional devices from such manufacturers as Dewalt, Makita, Hitachi and Metabo have also proven themselves well.

In addition, when purchasing a hammer drill for working with concrete, you should pay special attention to several indicators. Number of operating modes

Single-mode devices are not suitable for working with a concrete slab, since they are simple and have the functions of the most common drill. Dual-mode devices are capable of drilling (drilling with impact force); they are recommended to be chosen when you need to make through and blind holes in concrete. These types of hammer drills can simultaneously strike and rotate the drill; they are made of durable metal. Three-mode devices are also considered ideal for working with concrete surfaces. They are universal, perform impact without rotating the nozzles and quickly drill through concrete, revealing its hard structure

These types of hammer drills can simultaneously strike and rotate the drill; they are made of durable metal. Three-mode devices are also considered ideal for working with concrete surfaces. They are universal, perform impact action without rotating the nozzles and quickly drill through concrete, revealing its hard structure.

• Weight. Impact devices, depending on their weight, can be light, medium and heavy. Lightweight models are electric tools with a performance of up to 800 W, their weight does not exceed 4 kg. They are most often purchased for processing simple floors. For working with natural stone and concrete, it is best to give preference to middle-class devices that weigh up to 8 kg and have a power of up to 1200 W. It is possible to drill a hole in concrete with a diameter of more than 40 mm using heavy devices, their weight is more than 8 kg, and the impact energy exceeds 13 J.
• Engine location. Today, manufacturers produce devices with horizontal and vertical motor placement. Horizontal hammer drills belong to the simple class; they are easy to use, but cannot cope with concrete surfaces.

They can be drilled

only small holes. Therefore, if you plan to chisel large and deep holes, then you need to choose a tool with a vertical type of engine placement. It can work for a long time, since the motor is cooled better in this position.

Is it possible to drill metal with a hammer drill?

Even minor repairs, not to mention professional construction, cannot be completed without the use of a hammer drill. It is with its help that you can make a hole in a stone wall or a recess in a concrete structure. Therefore, both the home craftsman and the builder should know how to work with a hammer drill.

Also, such a tool allows you to quickly and easily drill the required number of holes in ceramic tiles, brick, wood, and metal. And additional attachments will allow, for example, to drill through a ceiling, compact material, drive a rod, and even tighten a screw.

Depending on the application and the availability of additional components, the hammer drill can be used in a wide variety of construction operations. But how to do this correctly to prevent tool failure?

For what materials can a hammer drill be used:

1. Is it possible to tighten screws and self-tapping screws with a hammer drill ? Many professional builders prefer, whenever possible, to use power tools that can perform the functions of several types of equipment. A hammer drill is one of them. To quickly and conveniently screw in self-tapping screws, special attachments are used. Among them there are models with a limiter, which guarantee control of the “recession” of fasteners.
2. Is it possible to mix the solution with a hammer drill ? It is possible, and quite effective, with low viscosity of the solution (for high-viscosity formulations, it is recommended to use a stirrer attachment and work at minimum speed). Additional arguments in favor of this use may be that the speed of rotation of the tool shaft can be easily changed. In addition, according to the principle of its operation, a hammer drill differs little from a construction mixer.

3. Is it possible to drill wood with a hammer drill? Using a hammer drill you can get fairly high-quality holes. To do this, you need to use a power tool in drill mode and use special drills. Depending on the material and diameter of the hole, the drilling speed is determined.

4. Is it possible to drill tiles with a hammer drill? The main problem when working with ceramics is that it can break if handled incorrectly. That is why, when using a hammer drill, you must first turn off the impact mode, and it is better to start drilling at low speeds with a gradual increase in speed.

5. Is it possible to drill metal with a hammer drill? If you use a special drill, it is possible to create holes with this tool in almost any material.

In most cases, they have a cylindrical shank and a spiral design. The material for their manufacture is high-strength steel (often based on cobalt alloys).

Drills equipped with carbide plates on the cutting part will be more universal in use.

General principles of drilling

As already mentioned, drilling is a common activity for a repairman, and therefore it is important to immediately learn several main rules associated with this activity.

• Introduction of suitable equipment. There are a huge number of drills, each of which is designed for a specific type of material. Therefore, you should not try to drill concrete with a wood drill and vice versa. It is also important to take into account the conditions in which the tool will be used. For example, industrial drills cannot be used for interior repairs (this is simply dangerous). It is also important to take into account resistance to moisture: for external work you will need a tool of class IP34 if the climate in the area is wet and IP32 if you have to work in good weather. IPX2/ can be used indoors
• Correct markup. Before starting any work, it is important to carefully and accurately mark the drilling locations with a marker. You can also stick cardboard tape under the marker so that the drill does not slip on the material.
• Selecting the desired drilling speed. It all depends equally on both the material and the diameter of the blade. If we are talking about very thin drills (with a diameter of less than 3 mm), then you need to work at low speeds, at least four hundred per minute. For other drills, the following rule applies: the thinner the drill, the faster the drilling speed required.

In addition, it is important to ensure that the handle is firmly attached to the shaft of the hand drill. The drill must also not be allowed to skew.

How to work with tiles using a drill

Often people who do not have extensive experience in the field of repair are afraid to drill into such fragile material as tiles. But this can become an urgent necessity, because you need something to strengthen the various cabinets and shelves in the kitchen, bathroom or toilet. As annoying as it may sound, in almost all cases the condition of the tile after drilling is determined not by the master who takes up the drill

, and the one who laid these tiles. A competent tiler lays the tiles so that no voids are created between the tiles and the wall. In this case, careful drilling will not harm the tile in any way. If there are “air pockets” between the wall and the tile, then most likely the tile will crack.

In order to drill through the tiles correctly, you need to take a drill, masking tape, or a hammer drill (or a powerful drill with drill bits for concrete). Then you will need to perform the following steps:

• The drilling location is marked with a piece of masking tape and a marker. The adhesive tape is there to prevent the nail from sliding on the surface of the tile.
• Drilling is done strictly perpendicular to the material. The number of revolutions should increase evenly: from unlikely to 150-200 revolutions per minute. This way you can effectively avoid damage to both the material and the tool.
• It is important to ensure that the drill does not overheat. If smoke starts coming out, the drill
  needs to be cooled down immediately.

Once the holes are made, you can insert dowels into them. This is done with a hammer.

How to drill through wood carefully

Wood is one of the “easiest” materials when working with a drill. But there are some subtleties here too.

• The drilling speed directly depends on the type of wood. Loose, not very hard varieties of wood will be possible even with a low-power device. Of course, the expected diameter of the hole also plays a role - the larger it is, the stronger the drill is needed.
• In order to make huge holes, you need to use special core drills. Their diameter can exceed 120 mm. As for depth, on average crowns are suitable for materials up to 20-22 mm wide, but there are also special models that can cope with widths of more than 60 mm.
• If you need to make a blind hole rather than a through one, then Forstner drills, which are available with a diameter of 1 to 5 cm, are perfect for this.

It is worth talking separately about drilling timber. Although it is comfortable to fix for upcoming drilling, the large thickness of the material makes it difficult. Drilling timber for future fastening in dowel holes. For a standard beam 18 cm wide, it would be best to take a drill with a diameter of 25 mm and a length of 36 cm. You will need to drill slowly, at low speeds. In terms of power, a 1300-1500 W drill is perfect. If the beam is not very long, then 2 holes on each side will be enough. If the length of the timber for the dowels is quite long, then you will need to make an additional hole in the center. After the holes are made, you can hammer them into the dowels using a hammer or a small sledgehammer.

Types and parameters of drills - distinctive features

When choosing a drill for concrete, builders ask how to distinguish its characteristics and make the right choice. Each product differs in size and is produced in a given diameter and length. One of the small drills for concrete work is 4-5 mm, it is no longer possible to drill a thinner hole of this diameter, its depth will be about 5 cm.

For example, with a diameter of 12 mm or more, the drill will be 1000 mm long, this will be enough to make a through hole in all walls except the bunker. The largest diameter is about 30 mm, it is not easy to work with, there is a heavy load on the hammer drill, and it takes a lot of time to cool down.

If it is necessary to make a larger hole, a core drill is used, which has a centering drill and a crown around it. Thanks to this, the process goes quite quickly, and the load on the hammer is small.

The core drill is coated with diamond coating or lining made of pobedit. A drill with a pobedit tip is set to the drilling and impact mode, with a diamond tip - to the drilling mode.

Drills from Pobedit

Pobedit as an alloy was developed in 1929, the main composition is cobalt and tungsten, where 10% cobalt and 90% tungsten. Effectively cope with brick, cinder block, concrete. The drill can be used to crush and cut concrete; it can withstand impact loads quite well, and no deformation of its cutting edges is observed. Steel products are subject to deformation and do not work as efficiently.

One of the advantages of the work is that there is no need to apply excessive force to the Pobedit drill.

Diameter selection

The diameter of the drill is selected taking into account the fact that when working with dense material, such as concrete, beating occurs during operation. As a result, the hole comes out slightly larger than planned. For this reason, the diameter should be taken slightly smaller than the planned hole itself. The length of the element indicates the greatest depth that the hole should be.

Most popular brands

The best concrete drill bits for drills from foreign manufacturers:

The products are considered to be of high quality, and therefore have a high cost, especially Bosch products, which have a four-spiral design.

Domestic manufacturers:

• Interskol;
• Bison;
• Anchor;
• Hurricane.

Drills have an average price category and, accordingly, a short service life. Products from a Chinese manufacturer can also be of good quality, but only if they belong to the appropriate price category. When constructing buildings in Moscow and other Russian cities, workers often use the listed product brands.

Concrete drill bits for drills - what and how best to drill

Comparing different types of tools, you can see that they have visible differences. Those used for drilling monoliths have a pobedite head installed. It is made of high strength metal. Pobedit allows you to drill concrete slabs and rocks.

Products with a reinforced head are used to process monolithic concrete slabs, metal, wood and other materials. The purpose can be determined by the color of the tip. White color is provided for concrete treatment. Black is used for drilling in metal, and a light shade of metallic color is used for drilling in wood.

If they are doing one-time repairs in an apartment, then they choose a tool at a more affordable price. During professional work, the need to work with this tool often arises, so purchasing well-made units is more important. At the same time, it is profitable to buy a set. Each part in such a set is purchased at a lower price.

Surface preparation

Before operating the device, you need to check whether there are any communications on the area of ​​the selected surface. If you neglect this rule, you can damage the electrical wiring or the place where the pipe passes. A metal detector will help the worker cope with this task, since when it detects non-ferrous metals, iron or steel, it gives a specific signal.

If the selected section of the concrete wall meets all the requirements, then you need to mark a point and then begin operating the device.

The intended drilling location should be marked with a pencil.

Errors when working with a drill

1. Clothes and gloves must fit properly.

Under no circumstances should you try to hold the rotating chuck with your hand - this is what the drill body is for. Otherwise, you may injure yourself. If you use gloves, do not take them “with reserve”. Gloves that do not fit properly may also become caught in the chuck and cause injury. Overalls should not dangle - they can be rolled up or pressed with sleeves.

• You should not press as hard as you can on the turned-on drill - this will cause you to fall, as it will become more difficult for you to control your balance. In addition, you may break the drill. If a tool passes through a concrete wall, the injuries it can cause to a person can be more than serious.

How to drill without dust: options, the better

Construction work is always accompanied by dust and debris, but using some recommendations and tips, it can be significantly reduced:

• During operation, the hammer drill leaves a slight dust, so that it does not fly around the room, use a construction vacuum cleaner at the same time. Some brands of tools have a built-in vacuum cleaner, which makes the task easier;
• using a drill, it is best to either make a jig on the end or a bag, or make an envelope under the hole so that the debris falls into it.

How to drill holes in a brick wall: choosing tools and attachments

To make a hole in a brick wall, a hammer drill with a drill or an impact drill are suitable; the latter is most often used. Its power must be at least 600 watts, the minimum number of revolutions is from 2500 per minute. It is best to use a drill with continuously adjustable power and a quick clamp function.

Using the hammer drilling function, the drill becomes identical to a hammer drill. Increases speed and ease of operation. To make a hole in a brick wall you need to use the dynamic impact method. Without this, the drill will not be able to engage the inside of the brick.

The drills must be victorious. If through drilling is necessary, a drill is used

How to drill a load-bearing wall with a hammer drill in a panel house

In most panel houses, the walls are made of concrete; in order to make a hole with a hammer drill, you need to use pobedit drills.

In addition to them, you can use special crowns. They have soldering around the circumference. When using them, you need to disable the hammer drill's impact function.

Specialists use diamond drilling, which requires powerful equipment and skills.

How to properly drill a reinforced concrete pipe with a hammer drill

When using an impact drill for reinforced concrete, you need to use the “perforator” mode and pobedit drills. First, the hole is made smaller, then larger. The drill needs to be cooled periodically.

Important! When working with concrete, you need to avoid hitting the reinforcement, otherwise the drill will break. Using a special device you can check where it is located

How to make a hole in a concrete wall with a drill

It is difficult to drill into a concrete wall with a conventional drill. You need to install victory drills and select low speeds. A dowel is inserted into the desired location to help the tool pierce the surface. Next, drilling should be alternated with striking the dowel.

The drill must be constantly cooled, otherwise it will burn.

If the drill does not have a speed control, then it will not be possible to make a hole.

How to make a hole in a concrete wall in an apartment with a drill

For a small hole, you can use a punch. Most conveniently, it can be made from a drill, 8 mm in diameter. The end is sharpened sharply. The drill is placed in the desired place, rotated, while simultaneously hitting it with a hammer. Wet the drill periodically to make it work longer.

What do the professionals advise?

Concrete structures are quite strong and difficult to drill. In addition, quite often drills come across crushed stone, which is part of the concrete mixture from which wall and ceiling slabs are formed.

Holes in concrete have to be made quite often, especially during the process:

• finishing works;
• furniture installation;
• air conditioner suspensions;
• additional electrical wiring device;
• installation of plumbing.

There are two ways to solve the problem of holes in a concrete wall:

• an impact drill, or better yet a hammer drill, with a Pobedit drill bit;
• diamond drilling.

It is worth noting that it will not be possible to make a hole in a concrete wall with ordinary drills, so before starting work you need to purchase drills with specially soldered plates made of high-strength pobedit alloy, which do an excellent job with concrete and brick. But it is not recommended to use them for soft materials, since pobedit drills do not cut them, but crumble them.

Difficulties when drilling holes in concrete

In the video tutorial of the article What is a dowel, we learned how to install dowels into a concrete wall, and at the same time drill it. However, there are situations that cause you difficulties when starting and during wall drilling work. In this article I would like to talk about such situations, and what should be done in these cases.

How to choose a drill for drilling reinforcement in concrete

The initial characteristic is the diameter of the hole, as well as the shape of the landing part. In this case, the drill is always designed for one-sided drilling, since for concrete surfaces it is almost impossible to align the axes of two holes that are drilled from opposite sides of the slab, wall or block.

How to drill reinforcement in concrete? In one pass, it is usually possible to obtain holes in the reinforcement if the maximum diameter of the cavity does not exceed 10 - 12 mm; in all other cases, preliminary drilling is performed first, and then reaming.

The choice of the size of the impact drill decides a lot. The disadvantage of a rotary hammer is that it sharply increases the level of vibration, and this will negatively affect the accuracy of the resulting hole. Considering that reinforced concrete has no plasticity, this circumstance will “help” break a hole or break off a piece of concrete along with under-drilled reinforcement.

Do I need to use a core or a bit? Experts think so. In addition, an impact drill with a rebar drill must be installed on a massive stand (or a tripod - when making vertical holes in the ceiling).

The best quality is obtained from hollow drill cores for reinforced concrete. They penetrate into the foundation only along the perimeter of the bit, leaving a cylindrical volume of concrete inside the tool. This piece is removed after drilling or periodically broken into pieces to ensure smooth operation of the drill. Drilling reinforcement in this way can be dry or wet (the second is preferable).

Specialized drilling tool

For example: exclusively for the needs of drilling reinforced concrete, the German company Bosch has developed equipment designs - ProDiager (drill for reinforced concrete) and RebarCutter (drill for rebar).

Features of the ProDiager line:

• Bit diameter, mm - up to 20.
• Durability before resharpening – up to 1000 holes.
• The number of bits in the holder is up to 10.

ULTIMAX's massive compact monoblock head is made from a carbide material similar to VK3, which allows drilling at the highest possible speed. Compatible with all types of powerful impact drills. Suitable for making holes and cavities in reinforced concrete, stone, granite and other materials.

The RebarCutter SDS plus-9 rebar cutter provides cutting of reinforced concrete and reinforcement embedded in reinforced concrete products. With the SDS-plus holder, the cutter can also be installed in conventional rotary hammers.

Specifications:

• The diameters of the resulting holes, mm – 16 – 32.
• Hole depth, mm – 120 – 300.
• Maximum tool runout, mm – up to 1.

Stationary models of rebar cutters are also available, which are equipped with a locking trigger switch. This cutter can be powered by a foot pedal, which improves the operator’s working conditions.

Selecting a drilling tool

Hammer drill

The potential of this tool when making holes in a concrete surface has no limits. Often they are limited by the maximum permissible diameter of the device, the size of which is no more than 5 centimeters. And at the same time, a huge part of such equipment can drill a hole with a diameter of 3 centimeters. Sometimes this may be enough, but there are situations when this size is not enough. For example, the volume of the hole for ventilation is supposed to be large and in such a situation the hammer drill will not cope with the task.

When operating a hammer drill with your own hands, another problem may arise. While drilling, you may bump into the reinforcement with the drill. This may result in damage to the tool. In the best case scenario, the hammer drill will stop on the metal and will no longer be able to work. It becomes clear that in the presence of reinforcement in concrete, operating a hammer drill is difficult, and sometimes impossible. But if working conditions do not require the presence of reinforcing bars, then this tool is an excellent choice.

Carbide bit

This equipment is distinguished by drilling holes with a diameter of 5 centimeters to 45 centimeters. But alas, the characteristics of a conventional hammer drill do not make it possible to install a crown larger than 25 centimeters. The reason for this is that the power rating of the tool is too low. If it is necessary to make holes of large calibers, then it is worth using a different tool. Larger equipment has a different shank shape. However, there are special adapters that make it possible to use large crowns on low-power instruments. But it is worth remembering that this option is not always profitable and safe due to the fact that the equipment may be damaged due to the installation of a large crown. And drilling holes in concrete using the thin method can be dangerous.

This device has some disadvantages that limit the capabilities of such equipment:

• Cannot drill through reinforcement. During a collision with metal, the carbide crown is destroyed. And while thin metal can be drilled, thick reinforcement cannot be drilled.
• If a crown is used, the concrete can be drilled to a small depth. This indicator is limited to the bowl. However, there are situations when using this device you can drill holes in a fairly thick wall and pipe.

The point of drilling a hole with a hole saw is to use the bit and pick one at a time. When the depth required for the crown has been reached, it is necessary to hollow out the center in the hole using a pick, after which the procedure is repeated until the necessary is completed.

However, in this case, another problem arises - the limited immersion depth of the lance. This nuance can be eliminated if a special extension for the crown is installed correctly.

It is important to know that when performing such operations with concrete there will be a lot of dust around
