The grinder allows you to quickly cut, sand and even peel off many materials, depending on the disc installed on the tool. The scope of use of such an angle grinder is constantly expanding. This is facilitated by accessories for grinders, the range of which is regularly growing. Let's talk about existing machines that are available ready-made or made to order. Let's look at the features of each popular option.

Basic information
Using a conventional angle grinder is not always convenient. After all, at least you have to hold it with your hands. However, a properly selected angle grinder attachment will allow you to use the tool more conveniently and get the maximum benefit from it.
Important! The rotation speed of the grinder is 12,000 rpm. Therefore, regardless of its use, all safety measures must be observed.
The use of specially designed and created additional structures allows you to expand the functionality of the power tool. At the same time, the grinder always remains the main working mechanism, and the devices are accessories. They are available in specialty stores. Their production is even ordered from specialists.
The grinder is a non-volatile tool for installation, construction and repair work. It was originally designed to cut, grind and deburr various materials.

Additional accessories allow the angle grinder to be used for trimming parts and performing milling work. The improved design is used for sharpening operations, creating grooves, making even cuts at the required angle and as a pendulum saw.
Important! Any well-thought-out attachment for an angle grinder allows you to increase the productivity of the work performed.
The choice of a specific additional accessory for an angle grinder depends on the area of use of the tool. The scope of its application affects the type of working disks. After all, manufacturers produce them in various designs for working with metal, concrete, and wood. Moreover, there are separate discs for grinding and polishing operations. However, they differ in grain size.

Store-bought accessories allow you to quickly improve your angle grinder. However, not every factory-made accessory has the necessary quality, which will ensure, for example, cutting accuracy. Therefore, it is not always advisable to purchase ready-made options. Sometimes the best solution is to order a so-called device from craftsmen who not only know all the intricacies of manufacturing, but have also personally tested the effectiveness of its use.
Of course, you can buy a grinder machine in a specialized store. After this, there is a possibility that it will turn out to be of poor quality and will not be able, for example, to firmly fix a power tool. Next, all that remains is to throw it away or give it to a specialist so that he can improve the device. With any of the options, a person will lose a certain amount of money.

- If you need to install two disks, grind off the washer.
- Place one disk and screw it in
- Then place the second disk and screw it in.
For family needs, such a wall chaser should be quite enough.
So what do you need to do for this?
For a small farm it is suitable for making and grinding feed (for chickens and hens)
So how to create such a crusher?
- We make a small hole in the existing sheet to fill in what is needed.
- Secure the grinder with bolts
- It is necessary to make a sieve with a capacity of 20 cm
- Make a 3 mm hole in the container; the grind size should correspond to the size of the hole.
- Attach the sieve to the base
- Cut out the bottom of the bottle and insert the neck into the base of the crusher
The easiest and most necessary way to create miracles. Currently, the grinder is an indispensable thing in the household and for every craftsman. There are many cool ideas, but the best ones are described in this article, which are developed and easy to use, the main thing is desire and everything is understandable.
Cutting machine
To conveniently, quickly and efficiently cut various steel parts, rolled products, etc., use a grinder attachment for cutting metal. This additional design to the angle grinder will allow you to perform precise cutting. With its help, it will be possible to prepare the necessary workpieces of the same size, make the required cuts, which will have the required depth. When you install a disc for concrete or wood on a grinder, it will be possible to cut ceramic tiles or lumber.
Specialized retail chains offer ready-made machines. However, they cannot be purchased at a low price. Such a device can be made by an experienced craftsman from an angle grinder with a power of at least 0.9 kW. In this case, the costs will be less than purchasing a high-quality machine in a store. A custom-made jig will allow you to make precise cuts. They will be no worse than a high-quality factory model.

Before manufacturing a cutting machine, its design must be carefully thought out. It should ensure reliable fastening of the angle grinder. To do this, first determine the dimensions of the machine, and to fix the angle grinder, think through the location of the fasteners. Usually the tool is clamped in 2 or even 3 places. It must be securely fixed to prevent its slightest displacement during cutting operations.
The angle grinder is secured on top of the worktop of a special table. It is also possible for the tool to be fixed from below. In this case, it will be possible to use a grinder attachment for an even cut not only of metal products, but also of lumber.

Important! Using a stationary machine is a safer way to cut various materials than carrying out operations when the angle grinder is held by hand.
Builders, finishers and other craftsmen use a simple or complex device for cutting metal with a grinder. The first version of the machine is an angle grinder attached to a workbench. This minimalist design implies the additional use of only fixing elements.
The second option is a machine of a more complex design. It is made to order or purchased ready-made if you plan to carry out large-scale work. Often the design includes a guide for an angle grinder for cutting sheet metal. It is also used when working with other materials. Thanks to this element, precise cuts of various workpieces and parts are made.

Characteristics that a belt for a sanding unit must meet
Selecting an abrasive strip is an important step when assembling a mini-grinder with your own hands. First of all, you need to decide on the length of the tape and its width. The geometric parameters of the strip are influenced by two main factors:
- grinder dimensions;
- purpose of the unit.
Fabric base withstands surface tension better
Endless abrasive strips are also classified into grit types. The length of the sanding strips can be different (from 610 to 1830 mm). Such tapes have a width of 50 or 100 mm. The first option is most often found in units assembled by hand at home.
A high-quality abrasive strip must have an elastic fabric base
When choosing the right tool, you also need to pay attention to how many revolutions the strip can withstand. It is recommended to purchase products that can operate at 1500 rpm
This option is best suited for making a belt grinder with your own hands. The drawing drawn up earlier must contain information about the dimensions of the abrasive strip and its other characteristics.
A good tape must have high abrasive resistance. The wear resistance of the tape depends on this indicator. For homemade machines, it is recommended to use belts whose length is no more than 123 cm. The abrasive strip must not only be resistant to wear, but also have good resistance to high temperatures generated during friction against the workpiece during operation.
It is worth noting that short-length tapes are much more susceptible to wear than longer products.
Experts advise paying attention to pictures depicting finished products. Photos of the machines allow us to answer the question of how to make a grinder with your own hands
The design of the device can be significantly simplified if ready-made elements purchased separately are used in its assembly.
The speed and quality of product processing depends on the choice of tape.
And finally, special attention must be paid to the place where the abrasive tape is glued. The junction of the two ends of the strip should be as neat as possible, without any defects or protrusions
How to glue the tape for the sanding unit yourself
Belt grinders contain a spring, which performs a very important function: it tensions the belt that has sagged due to wear. The belt is changed several times even when processing a small workpiece. This should be remembered.
When assembling a grinder with your own hands from plywood or metal, you can make an abrasive strip yourself. Gluing such tape is a complex undertaking that does not tolerate mistakes. There is a lot of advice on the Internet on how to properly glue tape, but many of them are incorrect.
The gluing process is as follows. First you need to select a fabric-based sanding material. Then you should prepare both ends of the abrasive strip. To do this, they are cleaned. The seam on the strip is made exclusively using the butt method. Experts definitely recommend reinforcing the glued tape from the inside with a thick strip of fabric, which is fixed with a special adhesive composition.
Gluing tape is a complex process that does not tolerate mistakes.
Note! Under no circumstances should you use Moment glue to glue the tape. In order to connect the ends of the abrasive strip, you need to purchase a special adhesive composition
The best option is to use elastic glue. There is no point in saving money, since cheap products, as a rule, are not of good quality.
In order to connect the ends of the abrasive strip, you need to purchase a special adhesive composition. The best option is to use elastic glue. There is no point in saving money, since cheap products, as a rule, are not of good quality.
Before gluing, it is necessary to prepare a strip for sanding tape. A do-it-yourself grinder (from scrap materials) needs a reliable abrasive strip, which is difficult to do at home. The process is carried out using a glue stick, which is installed on hot-melt guns. First, the composition is heated. To do this, you can use a regular hairdryer, which is found in every home.
Pendulum saw
This version of the so-called angle grinder accessory allows for high-speed cutting of various materials at the desired angle. This device is called a pendulum saw. A tool with a power of 0.9-2.5 kW is usually fixed in its frame. In this case, the dimensions and other design features of the pendulum saw depend solely on the model of angle grinder used.
This option is the perfect attachment for an angle grinder for cutting at 45 and 90 degree angles. After all, the instrument will be fixed motionless. This will allow you to make precise cuts at the required angle.
Pendulum saw from a grinder Source ad-cd.net
The pendulum saw has a not very complex design. It includes a metal platform. It has a slot that allows the angle grinder disc to go deeper. A metal corner is fixed on the platform. The workpiece to be cut is pressed against it. To securely fasten it, another element is used, which has a thread that allows you to clamp the part with the necessary force.
The design also includes the pendulum hinge itself. It is fixed on a stationary frame. The tool is fastened by using holes that are designed for installing a handle on an angle grinder. The angle grinder is fixed in a special bracket and using additional pins and bearings. The parts allow you to secure the power tool in the desired working position.
Such a device for an angle grinder for cutting metal is usually placed on a table, which can be made of wooden or steel parts. It is important that it is a stable and durable structure. Some craftsmen even use a workbench as the basis for an angle grinder attachment.

On a note! The cutting element of the pendulum saw must fit exactly into the slot of the platform or pass as close as possible to the end of the workbench or table if the angle grinder is mounted on a hinge directly near the edge of the supporting structure.
The mount for an angle grinder can also take the form of clamps. They are fixed on a pendulum handle. The clamps, which are tightened with bolts, are designed to attract the body of the angle grinder.
If the fastening is in the form of a rigid connection through the use of holes in the angle grinder, then it becomes possible to accurately position the power tool in space. You can even order a craftsman to make a device that will additionally include a protractor. It will allow you to make the most accurate cuts of various workpieces at the required angle. In this case, the protractor can be placed on the support platform or directly on the pendulum.

Accessories for an angle grinder – you can buy them, but it’s better to make them yourself
An angle grinder, simply called an “ grinder ”, has three main areas of use.
- Cutting hard materials;
- Grinding with abrasives;
- Cleaning surfaces with brushes.
The development involves holding the angle grinder with your hands during work .
However, for convenience and expanding the capabilities of the tool, many devices have been invented. Let's take a brief overview:
Tripod for angle grinder
This mini machine allows you to solve the main problem when working with an angle grinder: if you hold the tool with both hands, who will fix the workpiece? In this case, an angle grinder with a cutting disc is controlled with one hand, and with the other you can hold and move the piece of metal being cut.
Moreover, the tripod allows you to set the correct cutting angle, and the disk moves strictly vertically. The work is done efficiently and safely.
Craftsmen have long learned to make accessories for grinders for cutting metal and other solid compact workpieces on their own.
The frames are assembled from metal profiles, automobile shock absorbers, or even plywood. A well-made machine is no less reliable and safe than a factory one.
If your structure is strong enough and provides operator protection, you can use a tripod for sawing wood. The main thing to remember is safety. the cause of the injuries – an uncontrollable grinder that breaks out of the hands when the disc gets jammed in a tree – has been eliminated. But the disc itself can still cause injury.
Therefore, when manufacturing such a device, it is better to make the switch non-fixed. For example, in the form of a foot pedal. Then you can instantly turn off the power if the device
will get out of control.
When there is no need to work with wood, but only need to cut a large number of metal blanks, there are simpler options.
Such a mount can be made in an hour, and the ease of use will increase by an order of magnitude. If you know how your hands “fall off” after cutting fifty pegs from a metal corner, this design is for you.
Clamp for grinder
The second most popular way to add convenience when working with an angle grinder is to fix the tool motionless on a workbench or in a vice.
By installing the appropriate disk, you can get an excellent sharpening machine, or just an emery machine. The Bulgarian herself never ceases to be such. At any time , unscrew the mount and begin manual work.
If you attach a strong stop with a slot across the disk, you can process parts with high precision while holding the workpiece in your hands.
The most popular is the circular sawmill made from a grinder. Having made a strong frame and securely fastened the angle grinder under it, you get a seasonal sawing machine that can be easily disassembled if necessary.
At the same time, you still have a grinder and a great workbench (albeit with a slot in the middle of the tabletop).

This.
Miter box from a grinder
If the table top is angled, you will get an excellent miter box. Using such a device, you can quickly cut a plinth, baguette, or profile from any material at a fixed angle.
One has only to install the appropriate disk, fix the tabletop at an angle of 45 degrees - and cutting trim for the windows of a wooden house turns into a pleasure.
With this machine you can easily cut paving slabs diagonally, diversifying the ways of laying them.
Something similar is also available in an industrial version, but the cost of such devices will scare off not only the home craftsman, but also a small team of mechanics.
Wall chaser
Often, when laying electrical wiring or cutting passages in a wall, an angle grinder is used as a wall chaser. At the same time, comfort and safety during work leaves much to be desired. If you make an attachment for an angle grinder with a solid base, you can make cuts in the walls as far as the diameter of the disk is sufficient.
In essence, it is a support sole, which allows you to smoothly move the angle grinder along the wall, with uniform force. When you make this device for an angle grinder yourself, take the time and install a closed case with a pipe for connecting a vacuum cleaner.

Since any angle grinder is equipped with a powerful motor with a gearbox, a stationary milling cutter can be made from it.
Again, provided that at any time
the tool is removed from the homemade device for its intended purpose.
The shaft is inserted into the hole in the workbench, a chuck for milling heads is put on it - and you can process wood that is not too hard.
Sawing machine for porcelain stoneware
Working with stone requires special care. When the disk is tilted, you can damage the workpiece (which is not very economical) or split the disk. It is necessary to ensure the straight-line movement of the angle grinder, while simultaneously controlling the depth of immersion.
To automate the process, a special machine has been developed with guides along which the tool moves without deviating from the trajectory.
In addition, the cutting angle can be fixedly changed, expanding the processing capabilities. to make such devices with your own hands , but if you develop sensible drawings using computer modeling, you can design a machine no worse than a factory one.
Milling machine
It is often necessary to process flat and shaped surfaces of various workpieces. For this purpose, special cutters are used. They are part of the machine of the same name. Such a device for an angle grinder can have one of the following designs:
- An angle grinder is rigidly mounted vertically on a moving element of the machine, which allows the tool to move relative to the workpiece being processed.
- The angle grinder is fixed motionless in the device. Therefore, during milling, only the workpiece being processed moves, and the tool remains in place.
Any of the options requires a reliable frame. If the device is made to order, then the design will usually be suggested by a specialist, based on his experience and knowledge.
Of course, the customer can provide drawings that were developed by another specialist or simply downloaded from the Internet. In any case, the master will prepare all the necessary materials for the manufacture of a milling machine. You will also need to purchase a cutter holder. This is a collet device. At the same time, some craftsmen are able to make it from a hexagon.

✨19. Abrasive wheel “coral”
The sponge poly-strip grinding wheel with a diameter of 125 mm is designed for preliminary preparation of surfaces: removing rust, dirt and paint without dust and practically without noise.
The circle is made of nylon and silicon carbide, so it will remain effective for a long time. As for me, this is the best solution if you need to softly and smoothly clean metal from rust or paint.
After processing with such discs, polishing is practically not required. When working with “coral” discs, remember that they are afraid of sharp corners, so if you don’t want the disc’s coating to fly apart, be careful when working and avoid various sharp edges and corners.
Machine for ceramic granite
Only an experienced craftsman can cut porcelain tiles efficiently with a grinder held in the hands. After all, the material has a special structure that is highly durable. Therefore, it takes effort to cut it. At the same time, you also need to hold the tool level. Otherwise, you will get a crooked cut, which in most cases is not required.
A special cutting machine made from an angle grinder will allow you to perform straight movements with a power tool. Thanks to the device, it will also be possible to control the depth of the cut. Accurate execution of all movements will minimize damage to ceramic granite. Thanks to the smooth movement, fragments will not break off from the material and other defects will not appear on its front surface. This will reduce the number of defects when performing work. Therefore, it will be possible to reduce overall costs.

One of the main parts of a machine for cutting ceramic granite is the guide element. Thanks to its presence, the power tool will always move clearly along a given line. Many craftsmen offer to quickly make such a machine using blocks and plywood. All these materials are easy to process. Therefore, manufacturing the device takes a minimum of time.
How to make a frame for an angle grinder
It is obvious to everyone that it is extremely difficult to hold a heavy instrument for several hours. Therefore, to facilitate their work when performing an operation, many craftsmen make special devices called beds. When an angle grinder is equipped with such a device, cutting work can be done using only one hand.
To make a frame, you first need to make a wooden box. You can get by with only one side on which the tool will be attached. All other walls can be removed, and legs of a special design can be attached instead.
But in order to achieve the effectiveness of using an angle grinder with such a device, it is necessary to make some changes to its design.
The first step is to dismantle the casing of the angle grinder. After this, you need to put a disk on the instrument. When this action is completed, it must be pressed against the side wall of the device.
It is necessary to mark where the gap was made for the movement of the nozzle or disk. Its width should not be too large, otherwise foreign objects may get inside the structure during work.
If desired, the gap can be increased. The need for this arises in cases where it is necessary to replace the nozzles without completely disassembling the entire structure. Samples of wooden blocks can be used as support elements. After this, you can begin cutting workpieces.
Protractor for angle grinder
A convenient option is when the machine for cutting metal from an angle grinder is additionally equipped with a protractor. This device allows you to make the most accurate cuts if a person is working, for example, with a metal profile. Thanks to the protractor, the required cutting inclination is set. High precision must also be observed when working with various finishing materials, including porcelain stoneware and other tiles.
Factory protractor for an angle grinder machine Source ebayimg.com
The design of conventional transport consists of a corner. This element is a guide part. It is better if it has a pad that prevents movement and scratches on the surface of the part being fixed. The design also includes hinges and a fixing bolt.
To use a protractor, you must first press the workpiece firmly. Only after this is the desired angle adjusted. At the last stage, the workpiece itself is cut directly using a power tool.
The main element of the bed and what it is
The main element of the frame should ensure convenient sawing of metal with a grinder, since it is this element that turns a conventional angle grinder into an end grinder. To put it simply, you need to use some kind of pedal. To avoid a lot of explanations, we suggest taking a look at the photo below.
PHOTO: YouTube.com This is what the main element of the frame for an angle grinder should look like
In fact, if there is nothing similar among the parts in the garage or workshop, you can make such an element yourself. Similar designs are also found on limit switches of industrial guillotines and other similar equipment.
Grinding machine
One of the adaptation options is a grinding machine, which will function due to the work of the grinder. The most complex type is the tape device. This design uses two or even three rollers. One of them is driven by an angle grinder. Therefore, it connects with the power tool.
The rollers are designed to accommodate the belt sanding element. They are housed in a housing, which can have different shapes. If the machine is made to order, then the master will select and make the best option, which will allow you to conveniently grind specific parts.
The machine body is mounted on the table. The grinder is also necessarily rigidly connected to the entire system, subject to all safety measures. There are also lightweight options for manual use.

Another version of the grinding machine allows you to fix the grinder more often in a vertical position. The fastening is carried out to the metal supporting elements of the device. Most often they are made of metal corner. The actual fastening of the tool to them is carried out with bolts into the holes that were originally intended for the handle.
Important! The support structure for the angle grinder must be stable and rigidly connected, for example, to a table.
The grinding process itself is carried out with a special wheel, which is fixed on the angle grinder. Its grain size is selected for a specific process depending on the properties of the material being ground.
Sandpaper is usually used as an abrasive surface. Instead, craftsmen also often use a felt circle in their work. It all depends on the specifics of the work being performed.
On a note! Before attaching the angle grinder, it is necessary to remove the handle and protective casing from the power tool.
Work technology
triangle shaped cutout
Next, six holes should be drilled in the plate structure. The diameter of each of them should be 4 mm. Subsequently, it is in these holes that the self-tapping screws will be installed. With their help it will be possible to fix the handle, corners and timber. All holes must have special recesses for screw heads.
To securely fasten the beam handle, a few self-tapping screws are enough. The fasteners used during this work must have dimensions of 3x35 mm. This will result in an L-shaped part.
After this, all the elements together with the plate are assembled into a single structure. The created tool fixture must be secured using 3x20 mm self-tapping screws.
So, the basis of the future structure has been made. Next, you will need to install metal corners. You should have several of these items available. They must have the following dimensions:
- 75x30x55 mm;
- 45x60x60 mm.
Please note that the first corner must be bent to 60 degrees. If you don’t do this, then you won’t be able to achieve your main goal - to attach the manufactured structure to the angle grinder.
When the installation of the metal corners is completed, the tool itself is attached directly to them.
To connect the tool and structural elements, use a separate handle on one side, and bolts with nuts on the other side. The latter are necessary so that during work the screw of the structure does not unscrew.
If desired, you can refuse to install the nut on the handle, since it will be held by the hand of the master during work. At this point, the work on creating a cutting structure can be considered complete.
Miter box for grinder
Another useful device is a miter box. It allows you to quickly and accurately cut various workpieces at the required angle. This device will definitely come in handy when laying tiles, installing baseboards and many other finishing materials.
Often a miter box is used together with a special frame, which is a mount for an angle grinder for cutting at an angle of 45 and 90 degrees. This combination allows you to prepare blanks for assembling various frames. The miter box itself consists of a disk, which is placed under the angle grinder. It is usually put on a metal axle, which allows it to be rotated in any direction.
The disc has a slot. Thanks to the rotating design, it can be installed at any desired angle relative to the cutting element of the power tool. The slot is a guide. In accordance with its directions, the cut will be performed.
Important! The workpiece being cut must always be held motionless. The cutting angle on it is set in accordance with the slot on the disk.
How to make a circular saw?
Be sure to follow safety precautions, no things that can be wound, be careful with your fingers, no gloves should be worn. Materials:
Materials:
- Take a laminated sheet. This will serve as legs for the saw.
- We cut clearly along the line (either with a saw, or with a grinder, or with a jigsaw). We prepare the table and make a hole through which we screw the legs.
- Place the tool where you will attach it later, and also make the markings with a jigsaw or the same grinder.
- Re-attach and circle everything. Measure the hole and transfer it to the outline that you outlined.
- 5. Drill for fixation, make it wider than the bolt, about 1 mm.
- Attach the tool to the back side of the plasterboard. In order for the legs to stand at an angle of 90 degrees, you need to twist them from below with small blocks.
If you want to saw metal or iron, you can install a special disc for this.
Wall chaser from an angle grinder
This is another useful device that expands the scope of use of an angle grinder. After all, grooves are always made when building a house with stone walls. They are also created during major renovations.
Important! An angle grinder with a minimum power of 1200 W is suitable for use as a wall chaser. When installing discs for cutting concrete with a power tool, it will be possible to make furrows of the required width in the walls, ceiling and floor.
Each groove is created by cutting two parallel recesses in the building structures of the house. Therefore, a feature of the device is the installation of two working disk elements at once. They must have the same diameter. After all, the slots in concrete or brick must have equal depth.
On a note! Grooves are used for laying electrical cables and even pipes with a small diameter.

To install two cutting disks on one shaft at once, specially made gaskets are used. They allow you to secure the working elements at the required distance from each other. Bushings are also used. They fit on the shaft, so they have the appropriate diameter. These elements also allow the installation of discs with a large bore diameter. In this case, they must have a suitable external cross-sectional size.
Additionally, a casing of a different design is installed on the grinder. It allows you to close two cutting discs at once. After all, the standard casing has inappropriate dimensions.
Often the protective element additionally has a pipe through which dust generated during gating is removed. A powerful construction vacuum cleaner is usually connected to it.
In addition, a wall chaser for an angle grinder may have roller mechanisms. Their presence allows you to reduce the load on your hands. After all, the tool has to be constantly moved across the surface.
On a note! The advanced design is equipped with an adjustment unit. With its help it is possible to change the cutting depth of the discs.

All work with power tools is carried out in strict compliance with safety rules. Otherwise, harm to health is caused. In all honesty, electric shock may occur. In addition, dust harms the respiratory system, and sharp cutting elements can seriously injure a person.
Important! In addition to respiratory and eye protection, before starting work you need to check the operation of the electric tool at idle speed and the integrity of the electrical cable. It is also necessary to use working disks that are free of defects in the form of chips and cracks.
Homemade tool from an angle grinder
- second disk;
- thrust pad;
- protective casing.
To install the second cutting wheel, select an additional separating washer. The distance between the disks, as well as the width of the groove, depends on the length of the gearbox spindle. You can set the required distance using several standard nuts.
The first cutting wheel installed on the working shaft is fixed with a standard nut, which will serve as a separating sleeve. The second is fixed with a nut for the grinding disc, which is included in the angle grinder kit, but this nut is screwed up from the bottom. The resulting distance will be enough to cut a groove in the wall for electrical wires.
If the length of the working shaft allows, then the distance between the cutters is adjusted using spacer washers, or an installation sleeve is made. The grooves are wider and suitable for laying a pipeline or several wires at the same time. To ensure reliable clamping, the fastening nut is modernized - a sleeve with an external thread is welded on. After installing the first disk, the required number of nuts are then put on the bushing, thereby setting the required cutting width. To fasten another disk, use a standard nut from an angle grinder.
Since the grinder is not designed to withstand loads twice as high as the standard ones caused by installing an additional cutter, in order to prevent overheating or short circuiting, a break is taken every 15-20 minutes to cool the electric motor, gearbox, and commutator.

Briefly about the main thing
The grinder is already called a universal electric tool due to the ability to use it together with various devices. They are the ones who expand the scope of application of angle grinders.
The devices are available in retail chains in factory-made versions or their production is ordered from craftsmen. Bolkarka can serve as the basis for a cutting, grinding, milling machine. An angle grinder is used in the same way as a pendulum saw or wall chaser. An angle grinder even allows you to cut porcelain tiles evenly and quickly.
For an angle grinder, a protractor or miter box is purchased in ready-made wine or made to order. They allow you to cut workpieces at the desired angle. Cutting machines for angle grinders often have guides in their design.
Manufacturing.
First of all, I found the components for the hinge on which the angle grinder will turn. For a high-quality cut, the hinge must be powerful enough and without the slightest play.
I found an old shaft and flange from a Volga pump and several bearings, including dead ones. I assembled such a sandwich in order to push the bearings apart as much as possible.
I found a piece of pipe for the outer ring of the hinge.
It was a little large in diameter, so I made a longitudinal cut to clamp the bearings like a clamp.
I welded a couple of corners and drilled holes in the right places
The second component of the rack is a pendulum with a mount for an angle grinder. The angle grinder mount was bent out of a 2.5 mm strip.
The rest is made from a 20 x 20 mm profile pipe.
I welded the mount, trying to keep the angle grinder parallel to the plane of rotation of the lever as much as possible. To do this, when I was cooking, I inserted rods into the mounting holes and used them to control the parallelism.
The third component is the foundation. It is welded from angle 3 2x 32 mm.
Two 20 x 20 profile pipes in the middle are guides for an adjustable stop that should fix the workpiece.
The table was made from a 30 x 30 cm plate, 3 mm thick, sawn into 2 parts. Attached to the base with M5 screws.
In continuation of the table, a 3 mm plate is welded to the base. It is for attaching the return spring, and to align the table level further along the guides.
After all the fittings and adjustments, I assembled the stand together.
This is how the grinder is attached.
It is screwed on one side with a standard handle, and on the other with an M8 bolt.
Adjustment of the angle grinder vertically is done at the top and bottom using two stops (furniture legs).
The bearings are clamped into the cage with an M6 bolt.
The cage is screwed to the base with two M6 bolts.
The right hole is oval so that the position of the clip can be adjusted.
The return spring is from Volgov brake pads.
To prevent it from jumping off the mount, I made a galvanized clamp.
About adjustment:
In order to accurately mark the plane of rotation of the disk, I clamped two calipers into the grinder instead of the disk. Using them you can accurately and clearly adjust the position of the angle grinder.
First, I aligned the plane of the disk parallel to the longitudinal groove in the frame. To do this, one of the hinge mounting holes is made oval (marked with an arrow).
Then I set the plane of the disk perpendicular to the table.
This adjustment is made using two stops that secure the grinder.
When everything was smooth, I made a cut in the table with a grinder attached to a lever.
Now you need to make a stop to fix the workpiece at the desired angle. The blank for the stop was a piece of angle 32 x 32 mm, the same one from which the frame was made. I welded a 2 mm plate to it.
In order to cut a semicircular groove for the clamping bolt, I made a jig from the trim and drilled 3 mm holes in a circle.
Then go over them with a 6mm drill.
The jumpers between the holes were cut off with a hacksaw.
And he smoothed it out with a file.
Then I sawed off the excess in a circle.
From an already unnecessary jig and 2 M6 bolts I made a clamping strip for the stop. It is inserted from below into a groove on the frame.
The result is this emphasis.
It can move along the entire length of the guide groove and be fixed at the desired angle.
I haven’t figured out the design of the clamp yet, while I’m using a clamp.
The cut is smooth, neat, at the right angle - exactly what I was looking for.

Nozzle for angle grinder abrasive brush
This device allows you to use an angle grinder for cleaning wood, stone and metal surfaces. It removes rust, old paint, and any other old and persistent dirt well. Also, the brush can be used when cleaning welds.
The body of the abrasive brush is made of metal. It itself is made of polymer material. This provides a gentle effect on the surface being cleaned and allows you to work with materials that react differently to mechanical loads.
The nozzle is designed to work with grinders whose speed does not exceed 8500 rpm. Recommended speed – 4500 rpm.
Below you can see an example of wood processing with such an attachment.
