The grinder is a simple but extremely popular hand-held power tool that has managed to gain noticeable popularity in most types of technical and repair work. Its capabilities cannot be called too broad, as is the range of functional abilities, but the tasks themselves that the grinder solves are inaccessible to other tools.
Users appreciate angle grinders and are constantly trying to refine and improve the set of functions and capabilities. Let's consider one of these options that can make using the tool clean and comfortable.
Purpose of the dust collector for angle grinders
Modern construction technologies provide for a large number of works that are performed with the help of an angle grinder.
Cutting metal parts does not present any particular difficulties, but there are other technological processes that produce a lot of fine dust. Special attachments for an angle grinder will be needed when carrying out the following types of work indoors :
- Grilling floors or walls. In this case, a lot of dust is produced, regardless of the type of material. The greatest difficulty is that such work is mainly performed at high altitudes. In addition, debris falling from above settles evenly throughout the room. For these works, it is better to use a powerful bosch wall chaser.
- Cutting tiles . This is the most common dust process. Dust from ceramic tiles is considered the finest and most harmful to human health.
- Sanding wood floors. This is a very voluminous work that is performed over a huge area. That is why a lot of dust and small debris is released.
To successfully combat the formation of dust, manufacturers of angle grinders offer factory-made solutions to this problem. For example, it is recommended to install a protective cover for an angle grinder with a dust extraction under a Bosch construction vacuum cleaner. However, such a product is more suitable for large construction companies, since its cost is quite high. The home craftsman should make a homemade device that will be suitable for all types of work.
Causes of dust formation
The grinder is a universal tool. With its help, using various attachments, you can cut metal, stone, porcelain stoneware and tiles, process wood and other materials. But one of the disadvantages is the formation of a huge amount of dust. Work that causes the formation of large amounts of small debris:
- Grooving grooves on walls. The work is carried out using plaster, and cement and sand have a fine fraction. The height of the passage of the channels is at the level of one and a half or two meters. From such a height, dust settles evenly over the entire area of the room.
- Sanding of wooden structures. Before painting or varnishing, wooden products must be removed from the cellulose fibers that form during the sawing process. Cellulose is thin, light and hangs in the air for a long time.
- Removing old paintwork. Before applying fresh paint, the old paint must be removed. A flap sanding wheel is used. The paint it removes is fine.
- Cutting floor and decorative ceramic tiles. Sintered ceramic has a fine grain structure and it penetrates everywhere.
- Sanding parquet or wooden floors. Floor leveling occurs by removing the top layer. The irregularities have different heights and therefore, in addition to shavings, a lot of wood dust is formed.
Upon completion of the repair, dust must be removed from all possible cracks and cavities. To protect adjacent rooms from construction dust, protective screens made of polyethylene film or light fabric are installed in doorways. Special devices are also used that you can make yourself.
Homemade casing from a saucepan
In some cases, it is worth using a welding machine and making your own casing for an angle grinder for a vacuum cleaner from a thin metal sheet. This design will turn out beautiful and durable, but requires welding skills and expensive materials. If you have an old aluminum pan in your workshop, you can make a high-quality casing without using a welding machine.
For this work you will need the following materials and tools:
- aluminum pan;
- Bulgarian;
- measuring instruments;
- dye.
First, the main part of the dust collector is cut out.
It is necessary to carefully fit the casing to the electrical device. It is worth immediately accurately calculating the maximum penetration depth of the cutting disc, because the cutting height directly depends on this. mounting axis is cut out of the other part for mounting on an angle grinder. The diameter of the exhaust product is measured directly at the angle grinder. Its size must be as accurate as possible so that the homemade casing does not jump off due to high vibration during work. Experts advise using a strong tightening clamp when securing the device.
Using the same method, a universal pipe for the hose of a household vacuum cleaner is assembled. All edges of the product are very carefully curved inward along a single line to attach the side walls. Durable walls can be made from any type of material, for example, from a metal sheet. It is worth giving the device an aesthetic appearance, cleaning the joints and painting it with paint.
Complicated method
The second option will require an iron or aluminum pan. All actions take place in stages and do not require special skills in making additional equipment for the ushma. However, some tools are worth buying in order to do everything as accurately and efficiently as possible. And I wouldn’t want a hand-made protective element to cause injury.
Cutting out the shape for the angle grinder casing according to pre-measured dimensions
It is important to remember the saying: measure seven times and cut once. Why? It is unlikely that the spouse will be happy if, in order to save on equipment for ushma, she has to spend money and buy a lot of new dishes. From the remains of the pan, teeth are cut to the size of the grinder's torque sleeve
It is tightly secured to the grinder with a special clamp purchased in advance from the store. A cone is made from the same pan according to the size of the vacuum cleaner tube so that it can be tightly attached to the shape of the casing. It is worth recognizing that this may require considerable effort. It is necessary to cut a plate that exactly follows the shape of the future casing. And, accordingly, connect all the parts into one design.
The advantages of a casing made from a saucepan include the fact that there is no need to spend a lot, and you also do not need to have special welding skills. The negative aspects of this option include the scrupulousness of assembling the entire structure and, again, the inability to adjust the depth of the cutter.
Canister device
Home craftsmen have developed a more economical option for upgrading an angle grinder with a casing for a vacuum cleaner. In any workshop there will always be an unnecessary plastic canister for technical fluids. Such containers hold their shape perfectly, are quickly processed and have a factory outlet pipe of the required size.
To make such a product, you will need the following tools and materials:
- plastic canister;
- stationery knife;
- fastening materials.
First, fitting is performed, the main criterion of which is to ensure the required immersion depth of the cutting blade.
Use a utility knife to cut out the required through holes. Their sizes are selected taking into account further preservation of the maximum rigidity of the product. Both mounting holes are cut out on both sides of the canister so that you can change the direction of rotation of the cutting disc. The hose of a household vacuum cleaner is attached to the neck of a plastic container and secured with a clamp. Next, you need to attach the casing to the angle grinder using a strong clamp and a special adapter ring. The assembly of this part must be treated with extreme care. The hole in the canister is closed with a lid, which can be moved to the opposite side when changing the direction of rotation of the cutting disc.
Such homemade dust collectors cost almost nothing, but are very useful. A construction angle grinder with dust protection allows you to perform any type of work in rooms with the least emission of fine dust. To sand floors, the shape of the nozzle should be slightly changed, but this will not require a lot of time and effort.
Canister
If you don’t have welding skills or your wife flatly refuses to give permission to damage the pan, then there is a third option, how to make a protective casing with a dust extractor, which also miraculously connects to the vacuum cleaner tube. What will you need for this?
Find a canister in your garage, closet, or at your neighbor's. Using a construction knife or an ordinary knife, you will need to cut out constructive holes from it, in accordance with the shaft of the grinder and the location of the disk on it. It would be good to remember about safety precautions. Why? Trivial - to preserve the integrity of the hands
Moreover, it is important to choose the right knife. It should have a high-quality handle and fit well in your hand without slipping out
Afterwards, you need to attach the vacuum cleaner tube to the neck of the canister so that it becomes like a nozzle. How? Cut the neck lengthwise and put on a clamp so that you can then tighten the vacuum cleaner tube with it.
It is important to remember that in order to achieve good suction of the vacuum cleaner, it is necessary to ensure that all parts of the casing fit snugly against each other
Cutting ceramic tiles without dust
It is very difficult to cut ceramic tiles using a factory dust extractor, because the cover covers the cutting area, and the builder needs absolute control over the work. For this purpose, it is worth making a homemade dust collector from transparent materials, for example, from a large plastic bottle.
This fixture is secured using the factory protective cover. The neck of the bottle fits very well under the socket of a household vacuum cleaner. This homemade transparent nozzle will help you complete the most difficult jobs. The master will also be able to control the insertion of the cutting disc into the ceramic tile. Upon completion of work, you just need to throw the garbage out of the bag.

I made some kind of thing by stupidly welding two standard casings from an angle grinder and welding a pipe for a vacuum cleaner, a really useful thing, I leveled the hump on the wall with a diamond cup and there wasn’t a drop of dust.
One home-made man made a car body out of fiberglass - he said that he adapted to planing the surface with a plane. I tried, but it didn't work out very well. But planes are different and you need to be able to adjust them. There are also semicircular ones - like a rasp. You can also cut off irregularities with a chisel. In short, the grinder is the last thing.
As a rule, an electric plane is used to remove gelcoat from the bottom of boats when fiberglass is damaged by osmosis...
I meant a simple hand plane
Well, I don’t know if it’s sophisticated or not, but I saw his car, it’s cool, a sports car like a Pangolin (this was in the early 90s)
Now why recommend this? The 90s are long gone...
discuss options, suggest yours
Am I the only one who thought that if it’s skewed, this orange thing will hit your hand and injure your competitor’s hand?))) Well, it’s an unreliable crap. If you regularly saw, then you can make a normal casing out of metal. Or get a regular metal one from the collective farm. And you can’t even see the surface being sanded. How to blind sand?
Well, yes, so that if it flies off or gets twisted, it will certainly hurt your hand. Metal... why the hell would it fly off?
It’s better to compact it with a brush
I also did this, the current was made from two casings, it turned out OK, I used it to remove old plaster, the current made the exit direction along the angle grinder
Manufacturers
The most common and popular attachments are cutting discs. Bosch also produces good wheels for metal. The best diamond bits are produced by Hitachi (Japan) - such discs are universal and can successfully cut any material.
Sanding attachments from DeWalt from America are highly valued. They differ in the material from which they are made; they can be: sponge, fabric, felt.
To work with stone and metal, special abrasive attachments are used. The highest quality specialists are considered to be products from DWT (Switzerland) and Interskol (Russia). The products of the latter company stand out due to their combination of price and quality. The above companies also produce good grinding discs that are coated with diamond.
In addition, DWT produces high-quality angle grinder attachments called cutters. They are used to remove old paint, cement, and primer.
It produces a variety of turbine nozzles of very good quality. Prices for nozzles from this appeared on the market relatively recently, but it has already gained a good reputation and authority.
from China (Bort) also makes good attachments for grinders. As you know, products from Chinese manufacturers are traditionally low in price.
Making a casing for an angle grinder to connect a vacuum cleaner
When cutting metal with an angle grinder, sparks occur, and when processing concrete, stone, granite and other similar materials, dust is generated. If you cut wood with a grinder, a large amount of shavings will appear during the work process. In order to process concrete and wood with an angle grinder with minimal clogging, you will need to make a casing for an angle grinder for a vacuum cleaner. You can buy such an attachment for cutting power tools, but making the device yourself will help you avoid costs.
Purpose of the casing
As you know, any angle grinder has a standard protective cover. Its main task is to protect the operator from particles flying from under the tool and from flying debris in the event of a possible disk failure. If you make an angle grinder casing for connecting a vacuum cleaner with your own hands, then the standard casing is either used as a supporting base or removed from the machine.
The casing for connecting a vacuum cleaner to an angle grinder is used in many cases.
In construction:
- “cutting” a groove in concrete;
- sanding the rough coating of walls or floors for subsequent finishing;
- cutting finishing tiles or building stones (brick, cinder block);
- sawing wood or other non-sparking materials.
In metalworking:
- When cleaning surfaces from rust;
- Removal of old paint and varnish coatings;
- Sanding the material before painting.
Both lists are incomplete, and the need to simultaneously use an angle grinder and a vacuum cleaner is determined when planning the work.
What is the casing for?
Before you start working on concrete and wood, you will need to have a good idea of what the end result will be. When cutting with a grinder, dust is generated, which settles not only indoors, but also enters the human respiratory system. That is why work with the tool should be carried out exclusively in a respirator and safety glasses. To protect the room from excess dust, you will need to carry out work using a special attachment to which the hose from the vacuum cleaner is connected.
The attachment should be used on an angle grinder in the following cases:
- When chipping concrete, brick, cinder block, slate and other similar materials. If gating is carried out during the construction stage, then the settling of dust in the room is not as dangerous as during repairs. When cutting durable materials, they are crushed, which causes the formation of dust that settles throughout the room
- Cutting tiles and ceramic tiles - when processing these materials, dust is also formed, which is especially dangerous to human health. Tiles can be cut with special tile cutters, and no dust is generated, but if the work is done with an angle grinder, it is better to install a special attachment
- Wood processing - when sawing wood, not only dust is formed, but also sawdust, which can be eliminated very easily and quickly using a casing mounted on the grinder
Manufacturers make special casings for angle grinders with disc diameters of 125, 150 and 230 mm. These are the most common types of cutting tools, which is why manufacturers produce special housings for dust removal specifically for them.
Craftsmen and specialists do not even doubt that a casing is needed on an angle grinder, since it is enough to try cutting concrete once to be convinced of the need to purchase or manufacture a dust collector. What is better, to buy or make a cover for collecting dust on an angle grinder with your own hands, everyone must decide for themselves. After all, the protective casing is relatively inexpensive, but in order to avoid costs altogether, you should make the nozzle yourself.
Types of casings
Sanding attachment housing
The types of equipment for grinders that perform dust collection and removal tasks are quite numerous.
Manufacturers are aware of the problem and solve it by producing special devices for their equipment.
Based on the type of functionality, two options are available:
- for cutting discs;
- for grinding discs.
The first ones outwardly resemble conventional protection with a closed housing and a pipe for a vacuum cleaner. The second option is a closed lid with an outlet for connecting a vacuum cleaner hose. Both types are installed in the usual way on an angle grinder and do not require special tools for installation. Most users are familiar with the common models:
- Stomper SG-230;
- Stomper SG-230 R;
- BOSCH 1605510180;
- BOSCH 2605510107;
- BOSCH 2605510224;
- BOSCH 2602025285;
- Metabo GED125;
- Metabo GED125 Plus.
How to make a casing for an angle grinder for a vacuum cleaner - the best ways
The advantages of making your own nozzle are as follows:
- There is no need to spend money on purchasing a device
- Possibility to make a device according to your requirements
- No need to travel around looking for the right device
There are many options for making a casing for an angle grinder for a vacuum cleaner, and when making it yourself, it is not at all necessary to make the kind of equipment that has already been invented. It all depends on personal abilities, capabilities, as well as the available material from which the nozzle is planned to be made. To make the work of making casings easier, let’s consider several options for converting an angle grinder into a vacuum cleaner.
Required materials and tools
It is also important to prepare your tools. They will help you assemble the casing so that it serves for a long time and reliably. The following machinery and equipment will be required:
- crowns;
- screwdriver;
- construction hair dryer;
- step drills;
- cutting disc;
- vacuum cleaner;
- grinding diamond bowl;
- square, marker and screwdriver.
the grinder itself is also necessary , for which the casing . It will be needed for the final stage of work. After all the tools and materials have been collected, you can begin the main process.
We make a dust extractor from a plastic canister ourselves
The easiest and most economical option to make a casing for an angle grinder under a vacuum cleaner is to use a plastic canister as a base. To implement this version of the casing, you will need to take a canister of the appropriate volume. Usually a one- or five-liter canister is enough, but it all depends on the size of the tool itself.
The principle of manufacturing the casing is quite simple, and to implement it you first need to prepare a drawing according to which the dust removal nozzle is made. When manufacturing, the following factors must be taken into account:
- The size of the nozzle is taken into account, which depends on the depth of immersion of the cutting disc. The larger the size of the nozzle, the shallower the depth of the resulting cut.
- Holes of the required diameter are cut depending on the size of the bushing to install the device on the shaft of the power tool and secure it
- A hole is made on one side to secure the device to the shaft of the power tool. On the other hand, it is not at all necessary to make a hole, since dust can leak through it, which will reduce the effectiveness of the nozzle
- The neck of the canister is used as a bracket for connecting the hose from the vacuum cleaner. To connect the neck of the canister with the hose from an industrial vacuum cleaner, use a tie or clamp
To make such a device, you will need a minimum of time, effort and money. The result should be a device for removing dust when cutting concrete, tiles and wood.
Dust extraction from an old saucepan
If sheet steel is available, then it can be used as a basis in the manufacture of a dust extractor for an angle grinder. When carrying out such work, you will need a welding machine. If you don’t have a machine, you can make a nozzle from an old aluminum pan. The principle of making a device from an aluminum pan is as follows:
- The basis is taken from a part of the pan with the bottom. The bottom acts as one side of the nozzle, and the other side is made by bending the sides of the pan
- It is recommended to use rivets to connect sheet aluminum
- A hole of the appropriate diameter is drilled in the wall of the dust collector for fastening to the shaft of the power tool
- To secure the hose from an industrial vacuum cleaner, you will need to make a hole on the outside of the side wall to which to attach the neck of a plastic canister, bottle or plastic tube. It can be secured to the aluminum base using threaded connectors with washers
- The reliability of the connection between the hose and the nozzle is ensured by a metal clamp
How to make a casing for a vacuum cleaner for grinding with an angle grinder
If a grinder is used not only for cutting, but also for grinding, then to prevent the formation of dust in the room it is necessary to make a protective casing that will have a special design. Such a casing is somewhat more difficult to produce, but it is quite possible. As a base, you can use a five-liter plastic bottle, a CD container or a plastic bowl of a suitable size.
When making a casing for an angle grinder for a vacuum cleaner for grinding, the following factors must be taken into account:
- The working area will not be at the bottom of the tool, but at the side. To do this you will need to make a device with an open side part
- Make a reliable bracket for connecting the device to a power tool
- Connect the hose from the vacuum cleaner to the homemade workpiece
- To ensure contact of the sandpaper with the surface being treated, the walls of the device must be shorter than the protrusion of the abrasive nozzle
When performing work, you will need to use a hot glue gun. With its help, the production of ideas is not only simplified, but also accelerated several times. The result is an attachment for a grinder for grinding wood, metal and other similar materials. The entire process from A to Z for making a cover for grinding is described in the video material.
Comments
Removes 60-70 percent of dust. Great stuff. I only had to make a hole in the casing so that the M4 would be firmly attached.
If you cut iron with a cutting disc. with the attachment attached, will they have the same effect, that is, will a sheaf of sparks be sucked into the vacuum cleaner?

Good afternoon. Will your housing fit the Rebir LSM-125/1100E angle grinder?
I purchased this cover for the 125th angle grinder. Haven't tried it yet, but looks good! I hope it will perform its function well. My recommendation if you are interested. In reality, there are very, very few closed housings on the market that are purely for grinding. From what is available. only one casing of one well-known type of Ukrainian brand, plastic, not of the best performance. Two more available. Bosch and Metabo, but there is a price. space, besides, they are not universal, but specifically for the instruments of the same companies. Therefore, you don’t really have to choose, to be honest. You might be interested in trying to make one of your own, universal. But there is quite a big difficulty with it. it should be as small as possible, because if it is large. When sanding, it’s not possible to get into the corners, since the casing rests against the wall and that’s it. Therefore, making a high-quality and convenient product is not so easy. But I think you can do it! And there will most likely be demand. Thank you!
Application of cover for cutting tiles
The manufacturing options for the casings under consideration are suitable for removing dust when processing concrete, brick, cinder block and wood. When cutting tiles, one important condition must be taken into account - the accuracy of the cut. When working, you need to see the mark along which the power tool is guided, thereby making the cut. It is impossible to see the disk through steel or plastic casings, so when using a device for tiles or ceramics, it is important to make it from transparent materials. The easiest option for this is a plastic bottle.
It is not difficult to make a casing from a plastic bottle, and to do this you will need to make one hole in the wall for installation on the shaft, and connect a hose from a vacuum cleaner to the neck. It does not matter for which brand of angle grinder the device is made - Bosch, Interskol, Makita, Diold and others. All tools from different manufacturers have a similar design, so the manufacturing principle is the same for all.
Through the transparent cover you can control the movement of the rotating diamond disk. Moreover, it is recommended to use solid discs for ceramics, since segmented ones contribute to the formation of chips, and as a result the material may be damaged. Moreover, cutting must be done in one pass, otherwise the cut of the tile will turn out uneven. Having made a homemade casing for an angle grinder under a vacuum cleaner, you can test it in action, making sure of the usefulness of such a device.
Peculiarities
A housing for an angle grinder for a vacuum cleaner is a special attachment that allows you to protect the technician from exposure to dust, which flies out from under the disc when working with a grinding tool. Many hardware stores offer respirators for protective purposes, but these devices are ineffective. After a few hours of operation, they begin to clog, which means they cannot cope with their functions. Additionally, respirators are not designed to remove dust from a work area. Therefore, if renovations are being carried out in a residential area that has decorative finishes and furniture, it is necessary to use an angle grinder with a dust extraction.
Most designs of grinders include a dust collector. Thanks to it, dust is immediately collected from under the working surface of the device, without polluting the room. Such models are characterized by high suction power. They protect not only from dust, but also from debris. Additionally, a protective casing made of durable material is installed on the dust removal mechanism. It is able to withstand intense mechanical loads and, during surface treatment, collect different fractions, including small dust particles and pieces of metal or concrete.
The protective casing for a vacuum cleaner performs two main functions.
- Dust protection. It prevents the spontaneous spread of debris in the work area. The dust protection element also traps small and large pieces of debris that are formed during surface treatment. In addition, this device protects the tool itself from various particles entering the outer part of the body, which adversely affect the functioning of rotating parts and can subsequently damage them.
- Adjustment. The casing is not only responsible for dust removal, but also allows you to adjust the operation of the circle.
Since cleaning is performed with a vacuum cleaner connected to the nozzle, when installing the casing, it is necessary to ensure that the diameter of the dust extraction tube and the opening of the nozzle correspond to each other. The nozzle in the form of a flexible hose must fit exactly into the hole and fit onto the casing without any play.
It is recommended to use a housing for a vacuum cleaner in the following cases:
- For grinding concrete and chipping walls and floors. This type of surface treatment produces a lot of dust. In addition, most work is performed at height, and debris falling from above can settle throughout the room. To increase dust protection, you need to choose an aerodynamic or grinding casing that is suitable for powerful models of angle grinders and can withstand loads well.
- When cutting tiles. Such work is always accompanied by a large amount of dust, which not only pollutes the room, but is also harmful to human health. For this process, experts recommend choosing a cutting or universal casing.
- For sanding wooden floors. This process is quite labor intensive. It involves processing surfaces of large areas, after which a lot of debris and dust are generated. Thanks to the protective casing, scraping takes place quickly and efficiently, since the master does not need to be distracted by cleaning the work area. It is installed on an angle grinder using special fasteners.
The housing for the vacuum cleaner can be sold either complete with the tool or separately. At the same time, many craftsmen make protective devices with their own hands to protect the work process. A homemade casing is no different in functionality from a factory one, but may be slightly inferior in performance. Self-made casings can protect the craftsman from injury by preventing particles of the processed material from flying away. But if financial capabilities allow, then it is better to purchase finished products, as they are of high quality and allow you to expand the capabilities of the device.
How to use an angle grinder: tips and tricks from experts
The manufactured attachment on the grinder not only eliminates the formation of dust, but also acts as an additional protection for humans from the negative effects of power tools. An angle grinder is a life-threatening tool that is used for a variety of tasks. It is important to follow safety precautions when performing these tasks to prevent injury or injury.
Experts recommend following a number of the following recommendations when working with power tools:
- Hold the instrument with two hands only
- Use only suitable cutting discs and wheels depending on the materials being processed
- Do not get carried away with wood processing using an angle grinder. An angle grinder for working with wood is not the best option
- Carry out work in protective clothing - goggles, respirator, gloves, etc.
- Pause periodically to allow the instrument to cool down.
- When using a casing, it is necessary to ensure that it is tightly fixed to the power tool. If it vibrates, it may fall under the rotating disk and be damaged.
To make a homemade casing for an angle grinder to connect a vacuum cleaner, you will need to show a little ingenuity and imagination. Making a device is not at all difficult, and you just need to choose the right material to use as a basis. It can be not only plastic or metal, but also wood, for example, chipboard or fiberboard. And at the same time, you don’t need to buy a homemade device in order to ultimately carry out one-time work on processing concrete, wood or tiles with an angle grinder.
Features of cutting with a grinder
After choosing the equipment and the circle for it, before cutting concrete with a grinder, you need to familiarize yourself with the recommendations for carrying out the work:
The tool must be held with both hands
In this case, if a reverse strike occurs, it can be held, which will minimize the displacement of the cutting line; Work should be carried out only on a flat surface so that the person’s balance is maintained; The power cord should be located on the opposite side of the drive to prevent accidental damage to it. A cut cord can cause a shock wave from the unit and a short circuit in the electrical network; The tool must be held firmly in your hands until it stops completely; When changing the place of sawing, the grinder must be turned off so as not to accidentally touch surrounding objects; In the event of a power outage, be sure to disconnect the equipment from the network
This will prevent it from turning on when electricity is supplied without operator control.
Cutting concrete along a line
After the grinder for concrete has been prepared, work can begin.
- The cutting line is outlined. At the same time, it is advisable to fasten wooden blocks along the line, which will make the cut line more even;
- The grinder is turned on and a cut is made with a depth of approximately 5 - 10 mm;
- The bars are removed;
- A cut is made to the required depth. If the cut is made dry, the procedure should be stopped periodically to allow the instrument to cool.
The video shows in detail how to cut concrete with a grinder correctly. The process is best performed with the tool cooled.
- An ordinary spray bottle sprays water directly onto the furrow to reduce the amount of dust;
- Water is sprayed directly onto the disk, in the absence of a nearby power source. This will reduce the heating of diamond blades and extend their service life;
- If it is not possible to spray liquid onto the disc, cooling can be done with air. Periodically, the circle should be removed from the cut and given the opportunity to work in the air.

How to make a nozzle with your own hands
The following are videos demonstrating the process of making a casing for an angle grinder with your own hands. Craftsmen use various materials and technologies for production.
Homemade for gating, for a vacuum cleaner
Dust extraction covers are the most popular type.
Homemade protective casing for a diamond bowl from a plastic stand, corner and clamp
The base for the cover is a plastic stand for a flower pot.
A hole is made in the center: several cuts are made, the workpiece is heated and the edges are moved back.
A hole is formed at the edge for the PVC corner, which is then attached by soldering to the stand.
It is recommended to cover the rim with thick fabric or foam rubber to trap debris.
Casing made of a plastic bowl, pipes with a diameter of 40 mm. and clamp
To make it you will need a plastic cup and a pipe with a diameter of 40 mm. and a clamp.
A hole is drilled in the center of the bowl using a drill, “petals” are cut, and the edges are moved back by placing a pipe in the hole.
The workpiece is tried on a drill, the “petals” are cut off a little.
Using a clamp, the workpiece is attached to the angle grinder and made smaller in height; unnecessary parts are removed with scissors.
To make a dust extractor, another hole is made. The pipe is attached to the workpiece using wire stitching, and the joint is coated with silicone.
On the inside, the edges of the cover are covered with double-sided tape and door tape, which will keep dust out.
Upgrading the metal casing with a dust extractor and a curtain to adjust the cutting depth
Two plates of a similar shape are welded to the metal casing, thereby providing greater protection to the nozzle.
A hole is formed on the cover, a tube with a diameter of 25 mm is welded, i.e. dust removal is done.
There will also be a movable plate on the bottom side of the nozzle, which is secured using a curtain welded to one of the sides.
On the other side, a plate with holes for a bolt is attached. It is used to adjust the cutting depth.
Housing for an angle grinder for a vacuum cleaner
The grinder is not only a popular type of tool, but also easy to use. To use the tool, you do not need to have any special skills, but it is important to follow safety precautions. When working with an angle grinder, dust actively appears indoors when concrete, wood, and ceramics are being processed. Especially in order to avoid the occurrence of dust, casings for the grinder under the vacuum cleaner were invented and manufactured. With this device, working with an angle grinder has become even easier and more enjoyable.
How to choose a nozzle
The choice of a casing for an angle grinder for a vacuum cleaner comes down, first of all, to taking into account the size of the working disk. A casing larger than the working body itself will bring little benefit - it will be more difficult for the vacuum cleaner to collect all the dust. A good solution would be to make three sizes of nozzle, suitable for three main sizes of disks or plates
The next criterion for choosing a casing will be the type and quality of the work to be done.
- Sanding a surface treated with putty creates a cloud of fine dust. For such work, you need a casing with a tight fit of its edge to the surface being treated and a vacuum cleaner with high suction speed.
- When cleaning metal from rust, it makes sense to use a casing of a small size or with a transparent body for better control.
- Working with wood or removing old paintwork requires a casing of small diameter, but with a large outlet pipe - sawdust is larger than dust, a smaller diameter will clog faster.
- Sawing stones or cutting tiles also require high suction speed, since in this case the draft of the vacuum cleaner creates additional cooling of the space covered by the casing.
A comprehensive answer to the question about choosing the size of the casing will be the formula: “casing diameter = diameter of the working body (disk or plate) + 1-2 cm.”
The seat size of the casing is taken to be the diameter of the angle grinder body at the point of attachment of the standard protective structure, or the outer diameter of the support bearing seat.
The depth of the casing body is selected in such a way that its soft parts, fixed to the base, are no more than 0.5-1 cm long. The long soft edge can turn inward and get under the working element - the operator will feel a strong unpleasant tug, and the structure will come out of building.
Housing options for angle grinders
You can make housings for an angle grinder for a vacuum cleaner yourself, so there is no need to spend money on a factory attachment. In addition, there are more than enough options for making a homemade casing. Let’s look at a couple of options for making attachments for an angle grinder that will help you carry out work indoors “without noise and dust.” As for noise, the use of such attachments also reduces the noise level, although only slightly.
The first version of the casing involves the use of a pan. You can make a casing from a pan without much difficulty and even without the use of a welding machine. The only condition is the presence of an old aluminum pan. To make such a nozzle, you will need to cut out the casing from the pan, adjusting it to the size of the power tool.
It is important to know! The use of a material such as steel will not be relevant, since welding will be required to make the casing.
Having decided on the depth of penetration of the circle, you should remove the excess part of the pan, which can also be done using a grinder. In the resulting part of the pan, you need to cut a hole for the landing axis. The axle diameter can be measured directly using the grinder itself. The diameter must be as accurate as possible, otherwise the nozzle will slip off during operation.
In the back of the resulting nozzle, make a hole for the vacuum cleaner hose. This hole, called the dust chute, is where the vacuum cleaner pipe should fit into to suck out the dust. The presence of a dust collector or dust extractor allows you to perform the main task, to prevent the occurrence of dust in the room when working with a tool. At the final stage, the edges of the casing should be bent inward, with their help the side wall will be fixed.
The side wall for the protective casing of the angle grinder can be made of any material. It is best to use a thin sheet of galvanized steel or straighten the rest of the pan. A suitable piece of metal should be cut out and screwed to the main product with self-tapping screws. The photo below shows a view of the resulting casing for an angle grinder with your own hands.
You can also make a casing from a plastic canister. This option is also economical and even easier to implement. First you need to find an empty plastic canister, which is sure to be in the garage. We begin to take measurements, since an important condition is to ensure the required immersion depth of the circle.
It is important to know! The size of the required canister depends on the angle grinder. For grinders, a liter can of oil or brake fluid is suitable for a 115 mm disc.
The work of cutting out the casing is carried out with a construction knife. The neck of the canister should be left, as it will play the role of a dust outlet or for attaching a hose from a vacuum cleaner to it. We recommend cutting a hole at the level of the angle grinder axis, the size of the nut securing the working disk. This will make it easier to replace an erased disk.
After the product is ready, you can put it on the instrument and try it in action. It should look something like the photos above and below. Such a casing is not only easy to manufacture, but also does not require any additional costs.
Depending on the material and manufacturer, factory attachments will cost from 600 rubles, but is it even worth buying such a device when you can make it yourself without much difficulty. The above options are especially relevant in cases where you need to perform one-time work indoors, but at the same time you want to reduce the occurrence of dust.
Only a construction vacuum cleaner must be connected to a homemade or purchased casing for an angle grinder; it is designed to operate in this mode. We strongly do not recommend using a home version of a vacuum cleaner, as it will not be able to cope with large volumes of dust. It will very quickly fill (clog) with dust, which can lead to breakdown.
General recommendations for using an angle grinder
When working with a tool such as an angle grinder, safety precautions must be observed. A vacuum cleaner cover for an angle grinder is not only an option to avoid littering the house when doing work. The advantage of such a cover is that it protects the person doing the work from various factors. Working without a casing is like playing Russian roulette: you will be lucky or unlucky.
During operation of an angle grinder, negative consequences such as breaking the wheel are possible, which often happens with abrasive discs, as well as the occurrence of small fragments and stones that can get into the eyes. The danger of dust generated during the processing of concrete and ceramic products is that it can reach the lower parts of the respiratory system. It is strictly prohibited to carry out work cutting concrete or ceramics without a protective casing and a respirator. It is especially important to use a respirator and safety glasses if work is performed without the use of a protective cover.
An angle grinder is an indispensable assistant when performing various jobs. With the advent of such a tool, human manual labor has become much easier, but at the same time the likelihood of injury has increased. To ensure that the tool continues to be the best assistant in the household, design a homemade case for it, protecting yourself from possible serious injuries.
Self-production
It is not always possible to select a ready-made protective casing for an angle grinder with a dust extraction, since not all products have the same connection dimensions. In addition, they are not always available. The third limiting factor is the price - the Metabo GED125 model will cost 3,800 rubles, and the Bosch GWS 22-230 costs 13,800 rubles, which is 2 times more expensive than the grinder itself. Such prices force angle grinder owners to think about making dust protection themselves, especially since this undertaking is not particularly difficult.
People with a technical mind invent similar devices and remake containers that happen to be at hand for this purpose. As a result, fully functional, albeit unsightly-looking devices appear. They perform their tasks no worse than industrial designs, and cost practically nothing. Let's look at some options:
Homemade casing from a saucepan
Procedure:
- you just need to select the diameter in accordance with the size of the disk (2-3 cm larger). The easiest way is to attach the disk to the bottom, choose the optimal position and mark the center with a marker;
- then a segment is cut off that determines the amount of protrusion of the disk from the casing;
- a circle is drawn around the intended center, the diameter of which corresponds to the seat size of the angle grinder;
- A hole is drilled in the marked center, from which beams are cut from the center to the edges using metal scissors. The resulting petals are bent outward, forming a landing diameter for installation on an angle grinder;
- a metal clamp of the appropriate size is taken and carefully welded to the bent petals. Try it on the grinder and finally adjust it;
- a cutting disk is installed, its position is marked in a circle on the walls of the pan with a margin of about 1 cm. Then transverse cuts are made from the edges to the marked line, and the resulting petals are bent inward. Excess parts are cut off with metal scissors;
- the outer wall is attached to the bent petals in any available way - welding, bolts, screwed with wire. The material for it can be metal sheet, plastic, etc.
- The hole for the vacuum cleaner pipe is marked in the side of the casing. The pipe itself can be made of a plastic sewer pipe, or made of metal. The pipe is inserted into the hole, attached in an accessible way - by welding, screwed with wire, etc.
A home-made exhaust casing for grinding is made even easier - a pan of the required diameter is installed on the mounting hole, cut to height so that the grinder's grinding disc is completely covered with the remaining part. Then the petals are cut around the perimeter, about 5-10 mm high, and bent outward. A foam rubber seal for doors or windows is attached to them, which ensures the tightness of the casing. All that remains is to make a hole in the bottom next to the landing hole and attach a pipe for the vacuum cleaner. The casing is ready.
Canister device
A plastic canister bottle for technical liquids is convenient because it already has an almost ready-made outlet for a vacuum cleaner. The neck of the canister connects well with the hose; all that remains is to select the desired overhang for the disk and make a hole in the side flat part of the canister. You will need a clamp with an adapter ring that will connect the container to the grinder. This element is important, so it is necessary to make it as carefully as possible, otherwise during operation the dustproof casing will fall off the mounting diameter of the angle grinder. A slot is made in the narrow side part for the disk.
This casing is simple, lightweight and requires little time to manufacture. Old cans are lying around in any garage, finding them is not a problem. All that remains is to spend a little time and labor.
The prices for factory-made protection models are too high, so the vast majority of craftsmen use homemade ones. They do not require any expenses, are made from scrap materials and do their job quite well. It takes only a few hours to make, but the benefits received from such products are great and fully justify the effort and time spent.
