One of the most popular household tools is a (“grinder”), which very often becomes an indispensable tool for installation, repair and construction work for fast cutting of metals, stones and other structural materials. Thanks to various replaceable attachments, the scope of use of the grinder is not limited to peeling, grinding and cutting materials, but additional DIY accessories for grinders , greatly facilitate all operations with expanded installation capabilities.
There is a large assortment of attachments and devices that transform the angle grinder into a multifunctional machine that allows you to perform a number of additional operations:
For quick cross-cutting of metal and wooden measuring materials in everyday life, a stationary pendulum cutting machine is often not enough circular saw, on which absolutely any cutting wheels or saws can be installed. This machine is excellent not only for sawing angles, channels, fittings, wooden blocks, but also copes well with the task of processing stone and ceramic materials, which allows it to be used for “jewelry cutting” of facing tiles.
Do-it-yourself accessories for an angle grinder are quite easy to assemble, because you only need to fulfill a few conditions:
The do-it-yourself device for an angle grinder is a stationary frame with a pendulum-type hinge and quick fastening the Bulgarian herself. Manufacturing of the device is carried out in the following sequence:
Attention!!! Increasing the distance of the cutting point from the fence causes leverage torque, which can result in an uneven cut or clamp. cutting element with emergency manifestations.
Therefore, the thrust pad is installed a little larger and the excess edge is cut off immediately after assembly by the device itself.
The well-known angle grinder, with its cutting, grinding and cleaning capabilities, has turned out to be capable of several more functions. Expanding the functionality requires doing some work with your own hands in order to obtain the necessary devices for the job.
This device is a small machine that makes cutting easy, safe and very precise. metal pipes, profiles or rods. It consists of a base or small table attached to the ground or to a bench.
The machine is assembled in a simple sequence:
As a result easy work We have a machine or stand for an angle grinder. Now the grinder can rise and fall down on a hinge onto the part installed for cutting. In order for the angle grinder to rise up without loads, we install a spring on the pipe.
It is necessary to install two fixing angles on the table. At the base of one corner we make a groove around the circumference for a bolt. It will be needed when a pipe or profile needs to be cut at a certain angle. Then we install this corner with a slot at the same angle to the plane of the grinder’s cutting disc.
Parallel to the corner with the arc slot, we install a corner that can be moved towards the part to fix it on the table. The pipe or profile will simply be inserted between two corners. This is enough to perform fast and precise cuts.
By installing a supporting transverse metal bar on the machine table, you can strip the material using a steel brush mounted on the angle grinder shaft.
Angle-based cutting machine grinding machine You can do it yourself in one day. For the machine it is necessary to select a frame - a metal base plate. Attach the hinge to it. Weld a supporting frame with a plate for attaching the grinder to the hinge.
Any suitable part can be used as a hinge. IN in this case the hinge is made of rotary joints passenger car. The hinges have already served their purpose, but they fit the machine very well.
A groove is a groove that must be cut in the wall for installation electric wire or cable. The difficulty of this work is that the groove must be of constant width and depth. Then the wire will be laid evenly and less mortar will be required for laying.
A wall chaser is rarely used in practice, so buying one for your home will be expensive. But it can be made on the basis of an angle grinder - our favorite grinder.
The main task is to install two diamond blade on the angle grinder shaft with a distance of at least 1 cm:
But, if for some reason it is not possible to install two disks on the shaft, the groove can be cut using the usual method with one installed disk. You'll just have to cut a second parallel line.
Work with a wall chaser is carried out indoors. This creates a huge amount of dust. Even a respirator can't save you from it. To eliminate this negative phenomenon it is necessary to do protective cover, which would cover both disks and have a pipe on top for connecting to a vacuum cleaner. A similar device is available on electric jigsaws for collecting small sawdust.
Sometimes there are amateurs to this casing rational use The tool is equipped with 2 or 4 rotating rollers. When the wall chaser moves along the surface of the wall, it will move on rollers without creating additional stress on your hands.
To make a tool for a wide groove, it is necessary to make special bushings to mount the disks to the desired width. With such a wall chaser it will be possible to make grooves for laying pipes.
But the protective casing will also need to be made wider. It is necessary to install an immersion adjustment screw on the wall chaser casing for both wires and pipes cutting tool into the wall. In this case, the casing will consist of two parts connected by a hinge and a immersion adjustment unit.
Sometimes there is a need to mill a hole or surface, but there is no familiar milling machine operator, and there is nowhere to look. But there is an angle grinder - an angle grinder. This is the solution to the problem. We choose a machine from two options - a movable machine and a movable table.
In the first case, we secure the workpiece or material that needs to be milled, and the grinder is attached in a vertical plane to the frame. On the frame it is possible to move the plate to which the grinder is attached left - right and forward - back. In other words, we can move the angle grinder relative to the workpiece.
In another version, the grinder is fixed rigidly, and the workpiece moves, by analogy, left - right and forward - back. These are the main directions for milling. For milling along the up-down axes, it will not be difficult to supplement the device.
Having chosen the machine option, you can begin implementation. The only place that will require the involvement of a turner is the cutter holder. It is turned from a hexagon of at least 16 mm, because the thread of the grinder is 14 mm. Collet type holder. It is easy to manufacture and does not have large runouts. A regular jaw chuck does a worse job.
The advantage of such a machine, like all machines based on an angle grinder, is that they can easily be transformed back into an angle grinder. As a type of milling cutter, you can make a drill from a grinder.
It’s not difficult to make accessories for an angle grinder with your own hands. You don't even need drawings here. It is enough to know the principle that is embedded in a particular machine. A pendulum saw based on a grinder is no exception. This is the same cutting machine, but its weight is distributed almost in half.
It is somewhat similar to a children's swing. The frame is located on the movable bushing, and an angular Sander. The counterweight can be any weight in combination with a return spring.
For furnishing an apartment, cottage or cottage business people A grinder is often used. This device is, of course, useful, but when standing on a stepladder or in another important place you have to hold the grinder with both hands, which causes some inconvenience. And if this tool is large and heavy, then injuries may occur or the work may be rejected. Therefore, craftsmen have come up with and tested useful devices that make life easier.
Any device that allows you not to feel the weight of the grinder can be considered useful. So, several diagrams of a cutting machine appeared on the Internet, which performs similar functions. But here you will find new options.
Having assembled such a device, you can trim sheet materials, as well as sawing off parts of fittings and pipes. Grinding of tiles or stone is also provided. All this is provided by the cutting machine, regardless of what attachment is on the grinder.
Machine components:
A plate is used for the base of the bed. Slots must be made in it for welding angles and a spring ring.
It is necessary to cut out the movable part from a metal sheet and bend it at certain points. A 10 mm steel rod serves as an axis, which must be fixed approximately one third of the length of the pendulum part. Two 8 or 10 diameter screws are used to secure the spring to the rear of the device.
It is necessary to screw (or, if possible, weld on) the attachment point for the handle and the grinder to the movable lever. Particular attention should be paid to how reliable this fastener turned out to be. This will help avoid injury.
Triangles are attached to the frame, which must first be made from pipes. It is on them that the moving part of the machine rests. Small caps that are welded onto the triangles ensure that the axle will not jump off.
If it is not possible to make triangles from profile pipes, then, as an option, it is possible to produce them by bending them from sheet iron. The spring should be fixed on the frame ring and on the bolt.
A vice should also be secured to the frame - this provides greater convenience and cutting performance.
This is in many ways a unique device, which appeared quite recently, but has already proven itself well. The fact is that craftsmen often need to cut the pipe at a certain angle. So they came up with a special turning circle. It has holes and can be mounted on the frame - an axle is used for this.
First, you need to drill a hole in a horizontal plate (for this, use a hole in a circle corresponding to the frame). Thus, reliable fixation of the circle is achieved. A vice is fixed at the top of the circle.
The operating principle is as follows:
A rail assembly of furniture or other movable boxes serves as the basis for another useful device for cutting parts.
First you must remove two such mechanisms and screw them to the frame. To fasten the grinder, an iron plate is used, which is placed in the upper part of these mechanisms. A square is used to limit movements.
It is necessary that the bottom surface of the angle grinder is 1 cm from the frame, regardless of which attachment is used. If the size is not suitable, plates are placed between the frame and the rails.
The fact that people doing repairs have to hold large and heavy tools in their hands is a problem that reduces labor productivity and increases the likelihood of injury. But for the grinder they came up with a very simple device that makes work easier.
You will need two plates. The dimensions of one are 30*12 cm - it is made of steel. Textolite or duralumin are also suitable. The dimensions of the other component are 120*50 mm. It must be bent in the central part at an angle of 60.
Then a hole with a diameter of 8 is made in the second plate for attaching the grinder. For placement on the main surface, 4 holes with an arbitrary diameter are drilled. To prevent the fastening tool from coming loose from vibration, a bolt with a lock nut is used.
In addition, it is possible to use additional units that provide the most accurate cutting along the line. To do this, add a square, a corner and two wooden blocks to the plates.
The bars must be connected with screws. Also, 12 cm from the end of the square, a triangle is cut out and, like the bars, it is bent into “G” figurative form. Both the bars and the square placed on them are secured to the main plate with screws.
To ensure that the handle of the grinder is securely secured, a corner placed on one of the parts of the block is used.
When working, a person rests the device against the board. She is a limiter and directs his movements. Jerks are eliminated and a straight line is formed.
The second node is also used. It contains all the same plates. The role of a cutting limiter here is a square, securely screwed into the plate. It is also recommended to make special holes in the substrate. They will provide various sizes cut parts.
A homemade cutting machine made from a grinder (angle grinder), which can be easily made and installed in the garage, is a solution to problems in wood or metal work for those who often hold this tool in their hands.
Tools made from an angle grinder that you can make with your own hands can make working with this tool much easier.
The main advantage of the grinder is its mobility. But in some cases, when the workpiece is not fixed, and it is not possible to hold it due to the lack of an extra pair of hands, natural vibration appears. This phenomenon may lead to sudden destruction of the working disk, which is fraught with injury when its fragments fly away.
If you need to cut several parts of the same length with a grinder, and even strictly perpendicular, it becomes difficult to control the passage of the disk and take into account its thickness in order to maintain the specific dimensions of the part being cut.
In addition, there is always the danger of a kickback during the cutting process, which can also lead to injury.
In order to eliminate these inconveniences when working both on wood and metal, you can use tools made from an angle grinder, for example, a homemade stationary cutting machine from an angle grinder.
The main advantage of a cutting machine from an angle grinder is its mobility
If they are available, the angle grinder will work like a miter saw, which is much more convenient and safer.
There is a very simple way to create a device from a grinder, which will greatly simplify and save effort when working on wood or metal. In order to make it homemade machine, you only need a few working hours and the simplest components:
The assembled structure consists of a pipe, to which a plate with holes for attaching the grinder is welded, it is also a lever (handle) for raising and lowering.
The end of the pipe on which the angle grinder is installed is connected through a rotary shaft to an angle that is fixed to the work table or simply to the floor. A spring is installed in the same part to facilitate lifting the lever.
The main difficulty with this type of device for an angle grinder is the correct fastening of the tool. The saw (disc) must lower and rise along a path strictly perpendicular to the base (angle with a rotating shaft) and exclusively in one plane (without backlash).

A more complex version of the device from a grinder, which allows you to make precision work. To make it you will need the following components:
Before starting work, you should draw up a plan with parameters that are suitable for specific placement conditions and the type of work performed. You can copy it from a ready-made grinder device available for sale, or study all the proposed options posted on the Internet and choose the most suitable one.
First you need to make a frame, which consists of two frames connected to each other on a rotary shaft. This way they can be folded like a book cover. Sheet metal or a sheet of plywood (chipboard) is laid on the lower frame. Upper the frame must have fastenings for attaching the grinder, which will reliably hold it in a stable position under any load.
To fix the parts being processed, when working on wood or metal, it is necessary to provide a fastening device. This could very well be an ordinary clamp. It should be welded to the lower frame.
To make it easier to lift the upper frame, as well as to independently fix it in the upper position, you should install a sufficiently powerful spring that will be able to lift the weight top structure(frames with grinder).
To take measurements and set precise parameters, a ruler with a retractable limiter is suitable. This will ensure that the work is completed correctly.
To ensure that both hands are free when turning the machine on and off, it is recommended to install a foot pedal (switch). To do this, a power connection is made to the grinder through a low-voltage relay (12V). This measure is necessary to improve safety and ease of management.
An angle grinder is a very versatile tool. If absolutely necessary, do milling machine from a grinder with your own hands will not be a burdensome task, since The design is very simple and does not take up much space. At the same time, you can use it for milling work on metal not regularly, but as needed.
Necessary materials:
Every master always has his own workplace. As a rule, this is a table or workbench located in a room where noisy work can be carried out (garage, barn, etc.). This is exactly the table you will need for a device that will allow you to carry out milling work on metal.
At the edge of the near left corner of the desktop, a plate bent at a right angle is installed for attaching the grinder. The principle is that the attached tool should protrude beyond the edge of the table just enough for the disc to rotate freely.
For this purpose, a medium-sized disk is selected, and in the future, without moving the angle grinder mount, a larger or smaller diameter will not be used.
After the grinder is installed and secured, the profile pipe is installed. It should have a cut 2.5 cm deep and 2 mm wide than the thickness of the working disk (1 mm on each side). The pipe is welded to a corner, which, in turn, is mounted on the table in front of the grinder mounting plate.
Installed the fastenings must be positioned in such a way that so that, hanging from the edge of the table, the angle grinder with its disk enters the cut of the profile pipe.
Thus, it turns out that when rotating, the disk is surrounded on three sides by a profile pipe to a depth of 2.5 cm. This allows you to work on metal by holding the workpiece in your hands and resting it on a stand (profile pipe).
This kind of homemade installation can it work and how cutting saw, and in some emergency cases, it may well replace a lathe.
But not for metal, but for wood, if you provide for a stop for the cutter and a movable element for securing the workpiece.
Since the rotation speed of the blade is much higher than that of a conventional circular saw, if it hits a hard area, a kickback is possible.
Before starting work, it is necessary to let the machine run for several minutes in idle mode in order to make sure that the disk has enough space when rotating and does not cling to any obstacles.
The capabilities of an angle grinder can be expanded not only by various attachments, but also by installing it on special homemade devices. As a result, you can get a cutting machine, with which you can accurately cut metal workpieces at any angle. In addition, the grinder can be mounted on a carriage, and the resulting machine can be used for cutting sheet steel.
In order to understand how to make a cutting machine from an angle grinder (angle grinder), you can look at various drawings on the Internet. But they will be of little help, since all the dimensions of the parts will still have to be selected based on the size of the grinder you have. Options for making devices can be either simple or more complex, requiring the ability to operate a welding machine.
To make this device for an angle grinder, you will need welding skills. So, you need to do the following.
First, cut 2 small pieces from the corner (50x50 mm). Their size is selected based on the dimensions of the gearbox of your angle grinder.
Next, drill holes with a diameter of 14 mm in them and screw the corners to the angle grinder, as shown in the following photo. If you do not have suitable bolts, you can use M14 threaded studs. Just be careful that the bolts are not too long. Otherwise, in some models of angle grinders they may cling to the impeller located in the gearbox housing.
Without removing the corners from the angle grinder, secure them by welding. After this, the corners can be removed and scalded well.
Sand the weld seams using a grinder attachment.
Then you need to make rotating lever support, on which the device will be attached. To do this, select 2 pipes of such diameters that one can without special effort enter another.
For a more precise cut, you can glue onto the tubes masking tape and draw a line on it.
Then, turning the tube, carefully cut it with an angle grinder. A piece of pipe with a smaller diameter should be 20 mm shorter (the thickness of 2 bearings) - it will serve as a spacer.
For a thicker pipe, select 2 bearings suitable for its inner diameter. After this, insert the thin tube into the thick one and press the bearings on both sides.
Then insert the pin into the bearings. Be sure to place a washer in front of the nut.
When the rotating mechanism is ready, you need to weld a small piece of corner to it.
The next stage is done rack for rotary mechanism from the same corner 50x50 mm. To ensure that the pieces are the same length, the corners can be tightened with a clamp and trimmed.
Also, without unscrewing the clamp, they can be drilled immediately.
Attach the corners with drilled holes to the ready-made rotary block using nuts.
Weld a longer corner to this rack, as shown in the following photos.
Now you need to decide lever length, on which the angle grinder will be attached. This is done by selection based on the dimensions of your angle grinder. You can lay out the parts on the table and calculate the approximate dimensions of the lever, which is best made from 2 pieces of square profile pipe 20x20 mm.
The pipes also need to be clamped with a clamp and cut to the same size.
Once all the parts are ready, they can be welded together, as shown in the following photos.
In the next step you can attach to finished design Angle grinder and check again what came out of it.
Ready pendulum mechanism for an angle grinder can be easily installed on any flat surface, for example, on the workbench. This structure can also be installed on a table specially made for it. For a more rigid fastening of the mechanism, you can weld small sections of the corners on both sides of the long corner and drill holes in them.
In the following photos you can see how a ready-made attachment for an angle grinder is mounted on a table (in this case a metal frame is used).
It is very important to set a right angle between the plane of the cutting disc and the plane of the table. Place the square on the table and move it towards abrasive wheel, installed on the angle grinder. If you initially managed to weld the fixture so that the angle between the planes was 90 degrees, then that’s good. If you notice a deviation from right angle in one direction or another, then the situation can be corrected with the help of a crowbar or a long profile pipe, for example, 60x20 mm.
To prevent the part from moving when cutting, you can screw a corner onto the table that will serve as a stop. Also, for precise cutting, the table can be easily improved with a simple vice, made from a nut welded to it and a pin of the required length screwed into it.
Next you need make a protective casing. It is done taking into account the maximum diameter of the cutting disc, which can be installed on a specific model of angle grinder. To make it easier to determine the size of the casing and the places for its attachment, you can first make a template, for example, from a piece of cardboard.
In this case, the casing will also serve as a limiter for the cutting tool, preventing it from going too deep into the table while processing the part.
It would not be superfluous if for a lever with a grinder attached to it make springing. In this case, it's easy to do: insert with reverse side rod with a smaller tube and attach a spring to it, as shown in the following photo.
At this point, the manufacture of a cutting machine with your own hands, in which an angle grinder is used as a drive, can be considered complete.
Another version of the device for the grinder, with which you can cut metal blanks, is done as follows.
Thus, we got a simple cutting machine. To add additional rigidity to attaching the device to the lever, you can use clamps by first placing, for example, a wooden block between the angle grinder body and the pipe.
For precise cutting, so that the workpiece does not move, you will need to screw a corner to the table.
For a little Bulgarian A similar version of the device is also suitable, only the angle grinder will be attached to a metal strip: on one side with a bolt to the angle grinder itself, and on the other with a clamp.
For powerful angle grinders the device is made according to the same principle, but from profiles bigger size than in the pictures above.
It is not necessary to use dumbbells as a counterweight. All you have to do is find a suitable spring.
This device option is the simplest for making it yourself. It is made without a traditional stand (stand) for the rotating block. All you need is one door hanger, a metal strip, and an elastic band (you can use a rubber band from a hand-held resistance band).
The design is done as follows:
In just a few minutes you will get a high-quality cutting machine. This device is also mobile, because it can be carried with you in a suitcase with tools, and, if necessary, mounted on any flat surface.
When installing this device, do not forget to attach a corner to the table to rest the workpiece against it.
For cutting sheet metal will need to be purchased special carriage, which moves along a guide (profile square pipe).
But as practice shows, the cost of a good carriage is high (more than $100), so you can make it yourself. Since this process is quite difficult to describe, you can understand the manufacturing technology of this slider from this video. Using the device you can cut not only steel, but also ceramic tiles, and porcelain stoneware.
Please note that cutting ceramics generates a lot of dust. Therefore, it is recommended to adapt a dust collector with a pipe for a vacuum cleaner to the angle grinder casing.
The simplest dust collector for an angle grinder can be made from plastic bottle from motor oil.
The nozzle is made as follows.
After these simple steps, you can use the grinder to process materials that create a lot of dust when cutting.
