Drilling holes in artificial stone

I need to attach a sign to my artificial stone monument. What is the best way to drill into stone to avoid jambs, cracks and chips?

Artificial stone must be drilled with the same drill bits as concrete.

Namely, either Pobedit drills (with a Pobedit tip) or diamond-coated drills

You don’t need crowns with soldering, the holes for the plate are not large in diameter, drills are enough.

It is better to drill the monument without impact; a slab that is not very thick may burst.

It is better to drill with a hammer drill, it is heavier, but do not use a blow.

Turn on the blow if it is very difficult to drill into artificial stone, because they (stones) are made of different materials, concrete, porcelain stoneware, and so on).

The drilling process itself is not complicated; prepare water, make markings and mark the area for the hole.

If it is possible to lay the monument horizontally, then pour a small puddle of water onto the drilling site; the drill will not heat up when entering.

If the monument has already been installed, then frequently dip the drill into the prepared water.

If you do not cool the drill constantly, it will quickly “shrink”.

It is also important to remove the drill from the hole and clean the hole.

And of course, you need to drill from a smaller drill diameter to a larger one.

How to drill a hole in a ceramic sink

When does the question arise? Sinks without a hole were installed in Soviet bathrooms where there was one faucet for the sink and bathtub. Recently, this option has been used less and less, but sometimes, during budget renovations, apartment owners want to save on buying a new sink.

Sink without tap hole.

And so, you have a sink that has no hole. Working with ceramic sinks may seem like a lot of work, but you can do it if you follow the tips below. It's simple.

You will need:

1. Drill or hammer drill. 2. Drill (feather) for ceramics. 3. Crown for ceramics with tungsten carbide coating

Step-by-step instruction

To prevent the drill from moving, cover the area where you will drill with masking tape.
We make markings - put a dot with a marker.
Insert a ceramic drill bit into the drill and start drilling at low speed. Proceed with caution - ceramics are a very fragile material.
Use a smaller diameter drill first - for example, 6 mm. Then replace it with 8 mm. It is important to constantly cool the drilling site - water it with cold water.
After drilling the narrow central hole, switch to a bit with a diameter of 30 or 32 mm, depending on the diameter of the mixer.
Every 2-3 mm, take a thin drill and make small holes in the circle that the crown made. This is done so that the teeth of the crown can engage the edges of the circle and continue working.
When the hole is ready, you can install the sink in place.

How to drill a hole in artificial stone

Typically, sinks made of artificial stone come with an existing hole for the faucet, but there are options without it, or you need to drill an additional hole for the faucet for the water filter. What to do in such cases?

You can seek professional help, but if you feel confident, you can try drilling the hole yourself. But to do this, it is necessary to determine the material of the product - this determines which tool to use.

Porcelain tiles
Agglomerate
Acrylic stone

Porcelain tiles

The strongest and most durable of the entire group is porcelain stoneware. It serves for a long time and is durable, tolerates temperature and chemical influences well, so it is in great demand. But it is also the most complex material; it is most difficult to make a hole in it than in other types of artificial stone.

The best option for carrying out the work is to choose a crown for porcelain stoneware. It can be supplied as a set with or without a centering drill.

When working with porcelain stoneware, the drilling site should be constantly cooled, and the drill speed should be at the lowest possible speed.

You need to understand which side to drill from and when. If from the front side, after installation, the edges of the hole will be smooth and neat, but there is a danger that the drill will slip and spoil the appearance, for example, scratch or damage the edge.

If from the back, before installation, you are unlikely to damage the bowl, but perhaps the hole will have uneven edges. Basically it's not a big deal because they will be covered by the faucet.

Remember - the further the hole is from the edge of the product, the better. Don’t forget about the bowl so as not to get another, completely unnecessary hole - porcelain stoneware is both a durable and very fragile material. Therefore, the following rules must be observed:

Before carrying out the process, fix the sink, put chipboard under the bottom, this will protect the work surface.
Drill exactly perpendicularly, otherwise the drill may damage the glaze.
To prevent the drill from moving, cover the area where you will drill with masking tape.
Before work, wet the drill; while drilling, spray the work area with water, for example, from a plastic bottle.

Agglomerate

Milling cutter for working with artificial stone

Agglomerate is a softer material. Usually the sink already has a hole almost drilled. It must be knocked out with a core or drilled with the cutter included with the sink. If the kit does not include a cutter or core, then it is necessary to perform the work with a diamond-coated crown. The instructions are completely identical to the process of drilling porcelain tiles.

Acrylic

The third option is acrylic.
If your sink and countertop have color cohesion and create a cohesive space, then it's acrylic stone. This option is not difficult to work with. Ordinary drills are suitable for working with metal or wood. The diameter of the hole for the mixer is 32-35 mm. It can be drilled with a feather drill for working on wood products. The drill speed should be at medium or low speed. When working with acrylic stone, a lot of chips are formed, and a rather unpleasant odor appears from the plastic heated by the drill.

Where to cut the hole?

Another significant question that will arise no matter what materials the sink was purchased from is to cut a hole in it from the front after the installation has taken place? Or should I do this before installation and from the rear?

Each method has a number of advantages and disadvantages.

In the first option, the edges on the front side will be much smoother, but there is a possibility of damaging the front side of the sink with a drill, and if it has a narrow side, then splitting the edge.

In another option, the risk of ruining the bowl is much less, but there is a possibility of getting a sloppy edge of the hole on the front side. In many cases this is not a problem, since the edges of the hole are closed with a tap. When turning over, there is an option to unintentionally make a hole on the wrong side, so it is best to select the side on which you want to install the water tap.

How to work with a stainless steel sink

Manufacturers often produce stainless steel sinks without the special opening required to install the faucet. As a rule, such sinks are made of durable steel. This sink is very difficult to drill with a regular drill. A diamond-coated crown is barely enough for one hole (after that it will only be scrapped).

We offer for your consideration several options for installing a hole for installing a faucet on a stainless steel sink, although these tips are universal and are suitable for sinks made of ordinary steel.

Option #1

To drill a hole in it, you need to use cobalt drills (or tungsten, but they are more expensive) and a cutter. A cutter, or punch, is a two-part tool. It consists of a die and a knife connected by a bolt.

Read also: Working with an airbrush for beginners

Before starting work, the sink must be turned upside down. Next, we follow the following procedure:

1. Mark the installation location of the mixer with a pencil or bright marker. 2. Make a small dent in the center of the circle so that the drill does not slip off. 3. Make an initial hole using a 5-6 mm drill, and increase it to 10 mm with a drill of the appropriate diameter. 4. Install the punch (notch) so that the part with a smaller diameter is where the mixer should be. Tighten the bolt until the cutter cuts a hole.

Option No. 2

The second option involves drilling holes only for flexible connections and mounting stud(s). You can use the mixer pressure plate as a template. This option will save you from buying a cutter. But, in any case, you cannot do without cobalt drills.

Option #3

Here's a video as an example:

What to drill

Today, experts identify three types of tools that can be used for drilling ceramic tiles and porcelain stoneware.

Very often, diamond core bits with special galvanic coating are used to drill holes in porcelain stoneware. Among their advantages, it is worth noting their relatively low cost. If necessary, thin-walled crowns can be ordered. Such crowns significantly reduce the end pressure that occurs during drilling, and also allow you to increase the drilling speed itself. However, such crowns also have a significant drawback, namely the low drill life. One crown is enough for a maximum of five holes drilled in porcelain stoneware 8 millimeters thick.

Sometimes diamond sintered ring drills are used to drill porcelain stoneware. Most often, such drills are used for drilling concrete and other durable structures. The thickness of their working segment is 2 mm or more. However, such drills are rarely used, since their end pressure is greatly increased. Another disadvantage is the large amount of time spent drilling one hole. It takes about 3-5 minutes. However, despite the above disadvantages, such drills have a high drill life. They can make more than 100 holes before they become unsuitable for further use.

The best tool for drilling bathroom, kitchen and porcelain tiles, according to experts, are diamond drills. They combine the advantages of galvanic diamond crowns with high durability. All this is due to the high concentration of diamond grains in the tool itself. An example of such a tool is MonAliT drills. Their name stands for Monolithic Diamond Tool.

These are special drills from Russian manufacturers, developed on the basis of the latest technology for the production of diamond tools. A high concentration of diamond grains in such a drill is achieved thanks to vacuum diffusion welding technology. It allows you to increase the concentration of grains by as much as 2-2.5 times. When such a tool is sintered, a durable monolithic structure is obtained. Its pores are filled with metal, which makes holding the diamond even more reliable. Thanks to this production technology, it is possible to produce diamond drills with very thin walls. Their thickness does not exceed 0.8 mm. It is on the basis of this technology that drills for porcelain stoneware are manufactured.

Among the advantages of diamond drills, high drilling speed should be noted. So, it takes about 30-50 seconds to make one hole in an 8 mm thick tile. Such drills have a very high service life. If you use them for drilling porcelain stoneware without a drill stand, then they will be enough for about 50-70 holes. If you drill using a drill stand, then one drill is enough for 100-150 holes. In those cases when special equipment is used with cooling supplied to the drills, they can be enough for as many as 350 holes.

Another advantage of MonAliT diamond drills is their price. It depends on the specific type of instrument. The minimum price is 450 rubles, the maximum is 3200 rubles.

Drilling a hole

We make a hole in the artificial stone sink using a drill step by step:

To work, you will need a regular drill and a cutter with a diameter of 35 mm. As mentioned above, you need to place the sink on the back side and place a board and newspaper under it.
Next, mark the location of the mixer so that you can make a hole on the right side and avoid accidentally making a mistake.
To mark the center of the hole, you need to attach the nut from the mixer and mark its center. Try to keep the hole further away from the edges without touching the bowl.
Before starting work, make sure that the hammer on the drill is turned off. Begin to work carefully with the drill at medium speeds, avoiding allowing the cutter to move.
Prepare a small box for the shavings that are generated in sufficient quantities during the process. Passing through the plastic, the cutter heats it up and it emits an unpleasant odor.
When you finish drilling, clean the resulting hole from dust and chips. The size of the irregularities on the edge will not exceed a couple of millimeters: but they will not be visible under the mixer.

Do I need to drill all the way through?

There are at least two answers to the question of how to drill a hole in porcelain stoneware. Drill all the way until a hole is formed, and don't drill all the way through. In the latter case, there is one trick that can increase the service life of the tool.

With this approach, the hole is drilled to 2/3 of the required depth, and then the resulting ring plug is knocked out with a sharp blow from the front surface. In this case, part of the tile on the reverse side near the hole will be chipped off, but in this case such damage does not play any role.

The damage is on the back side of the tile, which will then be glued to the surface. Bearing in mind this method of drilling, as well as the possibility of chipping when drilling a hole to the end at the moment the drill leaves the body of the tile, drilling must be carried out only from the front side. In this case, all possible damage to the tile surface remains invisible.

Drilling holes in porcelain stoneware is quite possible, although it is a very durable material. Diamond drills are most suitable for this operation. In addition, there are certain subtleties outlined above, the observance of which will allow you to drill a hole in porcelain stoneware without much difficulty.

Punching a hole in the sink

Some artificial stone sinks have cast plugs that are knocked out during installation. They are usually color coded on the front. First of all, the sink is installed in place in the countertop, but is not fixed.

Then you need to choose the right tool and beat off the plugs with a strong blow with a hammer. A punch with a diameter of 8 mm is suitable for this role, but not a screwdriver. You only need to knock out the cork from the top: that is, from the front side. Use a rasp to smooth out the uneven edges of the hole.

Using this method, you can make a hole for the mixer.

The center is outlined and the circle is drawn.
Using a drill, holes are drilled along the circumference, the distance between which is 4 mm.
To prevent cracks from appearing when knocked out, firmly fix the sink.

If there is a need to increase the radius of the hole, you need to draw another circle of the required size. All cuts are made from the same front side along the circumference at a distance of 4 mm. Using a punch or chisel, remove unnecessary parts.

Answers from experts

Bulbasaur:

Manufacturers of sinks made of artificial stone are a little disingenuous when they claim that such material has properties similar to natural stone. In terms of properties it may come close, but not in terms of strength. An artificial stone sink is essentially plastic, or more precisely, a polymer mass mixed with stone chips. The proportions vary, from 20 percent crumbs and 80 percent resins, and up to 80 percent crumbs and 20 percent resins. In any case, drilling such material is much easier than natural stone. \

Valery:

It is necessary to mark with a marker the circumference of the hole of the required size and drill with a drill along the marker with a 5mm drill bit,

Daria Kalashnikova:

drilled

NOT OLD YET:

Don’t spoil the beauty, mount a wall-mounted faucet. Drill and you’ll be in trouble—a place where there’s a constant leak.

Andrey Kozmin:

Stainless steel is easy to drill. There are special stepped drills, you can simply drill according to the markings - then, no matter what, the trim closes. The main thing is whatever the mixer is.

Yuri!!!:

I don’t know the thickness of the metal, but the principle is such a small drill in a circle, then a needle file, etc. if the metal is thin, then drill into the center and use metal scissors to enlarge it. Stainless steel, by the way, doesn’t drill well (there are diamond bits, but I’m afraid they will cost more than washing)

Drifter of the Seas:

Mark the circle under the mixer with a marker, carefully drill out with a thin drill (3-4mm) along the inside of the marker, pluck it out with pliers

And I am Fsya Taka Zagadoshna:

A 32 mm cutter for metal, it is placed in a drill! Place a dowel or nail at the point where the hole will be (the tap will be located). To do this, you need to remove the sink. You can embed the faucet directly into the countertop; the hole in the countertop should be treated with silicone.

Winds:

and these sinks are not designed for a hole)))

The disadvantages of stainless steel with holes are that they bend and after a short time the fastening nut under the sink becomes loose and the mixer becomes loose - accordingly, there may be problems with rapid wear and tear. gaskets and leaks..

a hole is drilled in the countertop, the cut is treated with silicone, a washer must be placed (glued) under the nut - the mixer will remain motionless - acc. more durable.

Sergey Romanov:

There are crowns for metal, our price for them is in the range of 1500-1800, the hole turns out neat, but don’t forget to pour plenty of water, otherwise the edge of the saw will darken, they gave me good advice to drill with a small drill, just not 5mm, take a thinner one (it’s cheaper than a crown)

REM2009:

Drill 6mm in the center and then use a drill like this to the desired size. (in the jargon “carrot”) This drill in thin sheet metal allows you to obtain round, even holes; drilling by other methods is labor-intensive and requires additional effort to obtain a high-quality hole. (often used in car service)

the kindest of the kind:

on the market where sinks are sold, there is a special device, such as a clamp. Immediately squeeze out a nice hole for the mixer. The metal is thin, yes. On such a sink it is better to install a mixer with two valves, and if it is “one-armed”, then with a very easy movement. The fastening is a bit thin, the tap bends.

Mikhalych:

Isn’t it destined to put it on the countertop? there are no problems at all with drilling and installation.... Moreover, it can be installed from any side.

How to drill a porcelain stoneware sink

Among the above materials, porcelain stoneware is the most durable. Plus, this component is quite resistant to chemical and temperature influences and can easily withstand mechanical stress. Its distinctive feature is its ringing sound, which indicates the minimal presence of artificial additives.

The downside of such strength is the difficulty of processing porcelain stoneware, and it will be unrealistic to make a hole in such a sink with a regular drill. That is why in this case it will be possible to drill a hole using cutting tools (mills, drills, crowns) equipped with hard alloy tips (for example, diamond).

When working with such a tool, you should be very careful and not allow it to overheat, for which it is recommended to cool the drills (crowns) with water (supplied to the drilling site in a thin stream) and drill at low speeds (not higher than 400 rpm).

A plastic bottle with a hole in the lid can serve as a device for continuous supply of cold water. By pressing on a bottle of water, the resulting stream flowing to the drilling site will cool the tool well. You can find out more about the technique of cutting porcelain stoneware in the following article.

The cutting tool must be kept in water at all times.

What are the basic rules for laboratory furniture?

The most basic rule for laboratory furniture is that it should be ergonomic and practical. Conducting experiments and research of various types should be carried out in a convenient and well-planned environment. Different decor in such rooms is categorically unacceptable.

The second rule says that a table or some kind of cabinet, whether it is retractable or not, should be simple and multifunctional. For any business there must be certain furniture that will be responsible for a particular task. For example, a drying cabinet must be used only for drying.

The third rule is: laboratory furniture in Moscow

must be very durable, since it will have to withstand difficult loads. The strength of such furniture must be at the highest level; as a rule, laboratory furniture must be resistant to cracks. Often such furniture is made of durable material, such as plastic, metal or glass.

How to drill a sink from agglomerate

The second most durable material for making kitchen sinks is fragranite (silgranite), which is why it will be somewhat easier to prepare a hole in this element. In addition, many brands offer the user to simply knock out the required hole using a metal rod (8mm in diameter). Why are areas with prepared recesses provided in the product? This is done so that the user can independently choose the location of the mixer depending on the right or left position of the wing.

If you are not ready to use the proposed method (there is a possibility of chipping), then again you can use a diamond-coated cutter (crown) and make a hole according to the algorithm described above.

A more affordable option would be to use a Fostner cutter, which will also cope with the task. However, after a couple of such drillings, the cutter will not be suitable for subsequent use.

Often, agglomerate sinks provide places for knocking out holes, but despite this, many consumers complain that they cannot knock out a hole without problems. Since a visible chip may form on the front of the sink. To prevent this from happening, you should carefully study the instructions for installing the plumbing fixture, and only after that begin the work.

If we consider the manufacturer’s recommendations, then to punch holes in the product, you should use a metal core with a diameter of about 8 mm and strike at a strictly marked point on the front side of the product (usually the places for installing the mixer are indicated by a sticker of a signal color - yellow, red or green). If you try to perform this operation from the back of the sink, there is a possibility of chipping.

What you will need

When asked how to drill granite, many say that this will require some complex specialized tool, but this is not so

A regular electric drill is suitable for the job, it is only important that it has the option of adjusting the speed of revolutions per minute

In addition to the drill, you will also need:

a diamond-coated drill having the required diameter;
plain water.

First of all, you need to fix the granite slab as carefully as possible, making sure that the surface on which it is installed is as flat as possible. Before starting work, you should use a drill to mark the center of the future hole: this will help prevent the tool from sliding along the polishing surface. Install a diamond-coated bit into the drill (remember that using a non-coated bit will not allow you to make a hole).

Drilling should be carried out exclusively at low tool speed without using the punching option. When you turn on the perforation mode, the granite may crack. Regularly rinse the stone and drill with water: as already mentioned, this helps to cool, clean, and neaten the hole itself. In order to add water, you can invite an assistant. Or fill a plastic bottle with water, make a hole in the lid and use such a “sprinkler” to water the drill and hole yourself.

What to do if there is no diamond crown

If you don’t have a diamond bit and you don’t know how to drill granite in this situation, you can carefully stick a plasticine ring 3-5 mm high around the entire circumference of the future hole. Place a little corundum, pobedite powder or diamond dust inside the ring and add water. Attach a copper tube to the drill (you can use a tube from any other non-ferrous metal). Now you can drill granite - also at low tool speeds, without using a hammer drill. You will certainly need water here: first of all, in order to regularly cool the metal tube.

If there is neither a crown nor a tube, what to do?

In this case, craftsmen suggest using an emergency and risky drilling method - using a Pobedit drill, at high speed with a constant supply of water. During this process you will need to constantly sharpen the drill because it will stop from time to time

Sharpen the drill with a semicircular file, very carefully, without overheating its teeth. Otherwise, the drill will soften and become dull even faster.

Drilling on granite is a very difficult and painstaking job. It requires certain knowledge and skills. But if you wish, you can always purchase them by seeking advice from more experienced craftsmen. In order to practice, first use fragments of stone: this will help both “get your hands on” and prevent damage to a high-quality new workpiece.

How to drill a sink from acrylic stone

Due to the fact that acrylic stone is the least durable among the listed materials, it is easiest to drill holes in it. And even an ordinary wood drill can cope with the task. However, given that the standard hole for installing a mixer should have a diameter of 35mm, it is still more justified to use a pen drill or a Faustner drill.

In this case, you should work at low speeds, but at the same time make sure that microcracks do not form in the material, which is why you should work with a well-sharpened tool and ensure a constant drilling force.

By the way, you can read about how to drill ceramic tiles.

It is sometimes difficult to distinguish artificial stone from natural stone by its appearance. And in terms of strength and resistance to external atmospheric influences, in some cases it can even exceed it.

Types of decorative stone: agglomerate, acrylic stone, porcelain stoneware, artificial concrete stone.

It is very important that the weight of such stone and its cost are significantly lower than that of natural stone.

These qualities largely determine its popularity for the exterior and interior decoration of houses and apartments. It is also used when laying garden paths, equipping bathrooms, making countertops and window sills. Therefore, many DIYers are interested in how to cut such a stone, if you need to change its size or shape, how and how to drill holes, for example, for water pipes.

Artificial stone, made using different technologies, has different hardness. It depends on what components were used as filler and binder material. All such types of stone can be divided into:

agglomerate;
acrylic stone;
porcelain stoneware;
artificial stone on a concrete base.

Diagram of the hammer drill device.

Agglomerates, which include large quartz, granite, marble or limestone chips, and sometimes whole pieces of stone, bound with polyester resins, can be stronger than natural samples. The composition of acrylic stone includes fine-grained filler (up to 70%) and acrylic resin. This distinguishes it from agglomerates and makes it plastic when heated. It can be scratched or scorched.

Porcelain stoneware products are superior in hardness to ceramics and glass, since their main component is highly compressed kaolin clay.

Stones made from sand and cement or Portland cement are similar in properties to ordinary concrete. In some cases, manufacturers replace white cement with gypsum. Such artificial stones are less hard, can be easily processed, are cheaper, but are relatively easily destroyed under the influence of moisture and low temperatures.

How and with what you can make a hole

To process a material such as artificial stone, you can use the same tools as when working with concrete products. The tool used for drilling the hardest materials can be successfully used for drilling all its varieties. This is usually done with one of the following:

The grinder is used for drilling using special diamond bits, the design of which allows them to be used by screwing them onto a shaft to secure the disk. The crown is installed at right angles to the body of the angle grinder.

Drills or crowns are selected taking into account the size of the required hole and the hardness of the material used. As a rule, they have a carbide tip with pobedite tipped, diamond-coated or brazed diamond segments.

Clamps are used to secure the material. Dry drilling and water drilling are used to cool the cutting edge of the tool and the stone itself. In addition, water cleans the drill from sludge, and the edge of the drilled hole remains smoother. There is much less dust during wet drilling.

In order to drill with water at home, make a plasticine bath around the drilling site or place a rubber ring into which water is added. When using a template, water can be poured directly into it, sealing the cracks with ordinary tape. Sometimes water is simply added little by little from a plastic bottle.

Artificial stone can sometimes have a polished surface on which the marking lines are difficult to see. In this case, paper construction tape glued to its surface will help. The lines are clearly visible on it, even if you draw them with a pencil.

How to avoid possible mistakes

Unlike specialists who often drill the sink from the outside after installing it in the countertop, when doing the work yourself, it is better to make a hole from the back. This needs to be done for a number of good reasons, including the possibility of the edge of the product chipping off, especially if it has a too narrow frame, scratches appearing on its surface and many other negative consequences.

The only significant advantage of drilling from the outside of the sink is the ability to make a hole for the faucet with as smooth edges as possible. Yes, if the hole is made from the inside out, its appearance may be visually less attractive, but the sink will remain intact and unharmed, and after installing the faucet, this defect will also not be noticeable.

How to defeat porcelain tiles

For drilling porcelain stoneware, because it is very hard, use a drill with a special attachment.

Drilling porcelain stoneware is not easy; it is one of the hardest materials to process. To get smooth edges of the hole, you should always start from the front side. At the exit, the drill can make a chip, but in this case it will remain invisible. If the slab you are going to drill is not yet secured to the floor or wall, you should place a flat board or piece of fiberboard underneath it.

If the diameter of the proposed hole is more than 6-8 mm, you must first drill it with a tool with a smaller diameter. To work with porcelain stoneware, it is better to use a hammer drill or a fairly powerful drill.

The drilling speed is low or medium, it depends on the diameter of the drill. The larger the diameter, the lower the speed. It is better not to use a hammer; there is a risk of splitting the slab. In some cases, especially with a large thickness of material, a striker is used at low speeds if there are no voids under the slab, but everyone does this at their own peril and risk. When drilling, you must use water for cooling.

The best results are achieved when using diamond tools. In practice, different drills are used: carbide tips for tiles, a stylus with a diamond tip, diamond-coated tubes, and diamond bits.

Good results are obtained with thin-walled monolithic diamond-metal tubes made in China, and they are inexpensive, about a dollar per piece.

The drill wears less if you drill perpendicular to the plane of the material. To do this, a drill or hammer drill can be mounted on a vertical stand. In this case, the drill resource almost doubles.

It can be very difficult to start drilling with a crown on a smooth surface; it constantly tries to move to the side, scratching the surface. Therefore, to obtain a high-quality result, you can make a template in advance for holes of different diameters. The template is firmly clamped with clamps and prevents the crown from moving from the drilling point. You can also add water here for cooling.

You can start drilling at an angle to the plane if a template is not used: then the crown cuts into the stone with one side and then is leveled. But this method is better used on softer materials.

You can drill holes in stone using concrete and agglomerates in the same way.

Where to buy laboratory furniture at affordable prices

Innogen LLC is engaged in the sale and production of laboratory furniture. Today, the production of this company is in high demand in all CIS countries. The production facility is located on the territory of the Russian Federation, namely in the city of Pskov.

For the production of laboratory furniture, only high-quality and durable equipment for metal processing and painting is used. It must be said that laboratory furniture of the Expert brand has received a quality mark and is also fully certified according to all GOST requirements in Russia.

Over the past six months, I have answered the question of how to make holes in stones probably a dozen times. I decided to systematize it a little and tell it again, in general terms - now without any individualism.

There is a very simple method - ultrasound, but not everyone has the device, it makes a ringing noise, emits noise, is harmful and does not bring pleasure - however, it works wonders quickly and in capable hands. But we won’t even think about him, we’ll do it the old fashioned way

In relatively soft and non-fragile stones - such as malachite, serpentine, lapis lazuli - you can make a hole simply with a good drill for metal - clamp the drill into a drill, put the stone in water - if possible, secure it - and go ahead. You can simply keep a wet sponge next to the hole - the main thing is that it does not overheat.

If the hole is through, be sure to place it on another stone, it is even better to glue it with wax or paraffin, or even double-sided tape. Otherwise there will be a chip at the exit.

With harder stones the story is more complicated. Here you will need a tubular, diamond-coated drill. They are sold in special stores, such as Sapphira, and in ordinary good hardware stores, and much cheaper. Their diameters range from 1-1.5 millimeters to 12-15, and more are quite rare and very specific. I have the most popular 2-2.5 mm.

I cut such drills right away - I cut off the shank a little - then the drill is clamped deeper and does not hit, and this is very important

We take a stone, figure out why we need it, choose a place, put a mark, cover the bottom with a plaster and put it in a bowl of water. Two to three millimeters of water above the stone is enough. The adhesive will help the stone not to slide in the bowl and will at least protect it a little from chipping at the exit of the drill.

And we begin at low speeds, slowly but surely, pressing the drill in the right place

It is very important not to distort it. Every 15-20 seconds the drill should be lifted to remove debris from the hole

After a few minutes, a groove is formed - and the drill already receives direction.

The drill gets dull quite quickly, and doesn’t even get dull - it gets “greasy”, but this can be solved very simply - just put a piece of ordinary emery next to the stone and touch it with the drill from time to time.

When the drill goes a few millimeters deep into the stone, it is advisable to break the core column that has formed with a pin, a scriber, or a piece of iron and shake it out - then knocking it out of the drill is a little more difficult, although this is also not a problem.

When the hole tends to exit, you can start drilling from the other side, but this is only when increased demands are placed on the quality of the hole.

A little more and the drill will go easily - it means it has reached the surface, which is what we need.

That, by and large, is all.

In this case, a 4 mm cabochon was drilled in about a quarter of an hour, but this drill has already made dozens of holes in agates and flints, the new one works faster.

On paper (on the screen) everything is fast and easy, in reality it is a little more complicated, and not even more difficult - you need to be prepared for the fact that it will start to work out normally somewhere in the fifth or sixth.

I’d like to draw your attention to the following points: the drill is quite soft, its walls are thin, you need to clamp it into the chuck extremely gently. When you put the tip aside with the drill clamped so that it does not cling to anything, it bends instantly and practically does not straighten to its normal state

After work, be sure to immediately clean it from the inside, otherwise the sludge will dry out and there will be problems in the future. It is also better to drill soft stones with such drills - carefully and with dignity. You can also drill with a regular drill - it’s better to put it on its side, and constantly dip the pebble under the drill. And remember the rules for working with electrical appliances!

It seems that we can finish here about the holes

And one of these days I’ll try to continue about this agate.

Features of working with acrylic and plaster

All methods mentioned above are suitable for working with any artificial stone. However, acrylic stone has a more plastic structure and allows the use of tools of less high hardness. Drilling into acrylic stone is more like working into hardwood or aluminum.

Therefore, it can be drilled using ordinary metal drills; even a wood spade drill or a Forstner cutter will do. Large holes are drilled using a crown or tubular drill. Can be drilled dry.

Artificial stone cast using gypsum as a binder also does not require the use of tools of increased hardness. Sometimes to work with it they use a regular hacksaw for metal, or even wood, a mounting knife, an abrasive mesh or sandpaper. You can drill it with a simple metal drill if there are few holes. But for clean work, it is better to use drills or crowns with carbide tips.

Drilling can be done using a cordless screwdriver, selecting drills of the required diameter.

You can easily process a hole using a hand-held wood router by changing the shape of the hole or its size.

Is a pobedite tool used for drilling granite?

You can drill or drill into granite using a pobedite tool, but there is a high probability that the drill will not withstand the load placed on it. That is why, when choosing what to drill a stone product with, it is better to give preference to other types of tools. If you still haven’t found anything else to drill granite with and have chosen a pobedite tool, you should not use it in hammer drill mode.

When drilling, carefully monitor its effectiveness. If it has noticeably decreased, then you should stop processing and sharpen the drill, for which you can use a semicircular needle file. A pobedit tool used as a drill for working with granite will have to be sharpened quite often: once every 60 seconds.

How to give a slab the desired size and shape

At enterprises, artificial stone is cut on stone-cutting machines with coolant supplied to the cutting site, and laser or waterjet cutting is also performed. The last two methods allow you to give the stone the most amazing, even curvilinear shape.

At home, the choice is not so great. This problem can be solved using a hand-held circular saw or plunge-cut saw, selecting a blade that matches the material being cut. An electric tile cutter will also do the job well.

Electric tile cutters are equipped with a small coolant bath located under the cutting table. Based on their operating principle, there are two types of tile cutters. In one case, the disk is installed motionless, and its work table with a stone attached to it moves. In the other, the disk, together with the drive, moves along guides above the cutting plane.

All of these devices work with diamond blades of various configurations, solid and segmented.

If the relief and thickness of the stone tile allows, it can also be cut using a manual tile cutter.

But the most universal tool for cutting stone is considered to be a grinder with a diamond blade. It is advisable to choose a disk of large diameter. Different discs are available for different materials.

To cut cuts in stone, they sometimes use a jigsaw or a diamond string. There are also special stone blades for a regular hacksaw for metal.
