The grinder consists of electrical and mechanical parts. During operation the electric drive may burn out , even if the gearbox is in good condition. The opposite option is possible - the gearbox parts (cracks have appeared on the housing, the gears have worn out, the bearing units have failed) are critically damaged , even if the electrical part of the angle grinder is working properly. In such cases, some craftsmen do not write off the entire grinder as scrap, but try to find a use for its serviceable part . The most inventive ones, after purchasing a new angle grinder, find the use of an entire previously used angle grinder in other mechanisms that require an electric drive and gear transmission.
Making a wall chaser
What can you make from an old grinder? Home craftsmen ask themselves this question quite often. But if your angle grinder works properly, you can use it to make a wall chaser. By using equipment without modification, you are putting yourself at risk. In order to avoid risk, you can make a nozzle with a solid base, which will allow you to make cuts in the walls over the entire diameter of the disk.
This addition is a footplate in the form of a stop that allows you to move the tool along the wall. The efforts will be uniform. When you make such a device, take the time to install a closed cover, which will be supplemented with a pipe for connecting a vacuum cleaner.
Types of devices, their advantages and disadvantages
There are two types of designs of cutting machines, differing in the location of the grinder, which can be made at home.
The first installation is a frame with an angle grinder rigidly fixed underneath it. Only the cutting disc is visible on the working surface, which fits freely into the table slot. Cutting a metal profile or sheet in this case is completely identical to cutting wooden blanks using a circular saw. Despite the very simple design, this scheme is not particularly popular. Those who have made such a device note that it is inconvenient to use due to the need to move the workpiece. This significantly reduces the accuracy of the work and makes the process unsafe. The only advantage of a machine with a bottom angle grinder is the ability to quickly cut thin metal sheets.
A cutting machine with a lower angle grinder can be used both for cutting metal and as a circular saw
The second scheme, in which the part remains stationary and the cutting wheel itself moves, is more convenient. The so-called pendulum saw, placed above the tabletop, allows you to cut the workpiece exactly at the required angle, and it becomes possible to make the required number of parts of the same type. Due to the location of the grinder on top, cutting workpieces does not require effort, and operation of the unit becomes simple and safe. The undoubted advantages of the design include the ability to quickly dismantle the grinder for traditional use. As for the disadvantages of this method, the weak link can be considered the hinge joint, which complicates the design of the machine.
A machine for cutting metal with an upper angle grinder has a more convenient design and makes it possible to cut workpieces at the desired angle
Working on the frame and ruler
The simplest frame will consist of frames mounted on the same axis. The lower one must be fixed on the platform. If the tool is large, it is better to use metal. A grinder is screwed to the upper frame, which will rotate vertically according to the principle of a pendulum. A spring is needed to fix the original position.
A fastening is welded to the lower frame, which will consist of a clamping angle and a clamp. The machine should be equipped with measuring parts. In this case, a moving ruler with a limiter is better suited. It is welded to the pipe.
Features of making homemade products from a broken tool
The grinder is not an eternal thing, so after it fails, you can use the equipment for other homemade products. Sometimes it happens that the engine or gearbox . The housing may break or gear teeth may be cut off. However, there is no need to rush to throw away the device. One of the two units of the grinder may still work.
If you are deciding what to do with a broken angle grinder, you should consider the engine. But due to its high speed, it is rarely suitable for alterations. This part of an angle grinder can only be used as a basis if an engraver is manufactured. You will need to cut off the gearbox and attach a chuck to the shaft for different attachments; there are a huge number of them on sale.
If you are still interested in the question of what can be made from an angle grinder whose engine has fallen off, you can use a gearbox . It is metal, compact and has a powerful bearing on the output shaft. Due to the existing threaded connections, the gearbox has good mounting options. The gearbox can be installed on a drill using a special adapter. But on such tools, the cutting wheel can be a source of danger. Therefore, it is recommended to adapt the gearbox to situations far from the original function of the angle grinder. For example, you can make a sander for wood floors. You can carry out this dusty work comfortably by adjusting the speed and bevel gear. A larger area can be covered with a wide disk, which speeds up the process.

Quite often, home craftsmen think about what can be made from an angle grinder gearbox. The cone assembly is compact, so it can be used for a variety of setup and adjustment tasks. For example, to adjust the work table on a machine. The gearbox is widely used to create boat motors. The issue of sealing the propeller shaft can be solved by sealing. Outside the gearbox, you can install an additional oil seal on the propeller shaft under the cover ring. But in the case of motorized bicycles, a seal is not needed.
But if you are still interested in the question of what can be made from an angle grinder, you can use its gearbox , transferring the torque to the wheels. The described unit is installed on the wheel axle. By using a traditional chain, you can use the protective standard casing as a holder for a gearmotor. You don’t have to limit yourself to an electric motor by using an internal combustion engine. The grinder gearbox in this case will be able to withstand even high loads.
When thinking about the question of what can be made from a grinder, you can consider making a coffee grinder. It is suitable for lovers of an active lifestyle who prefer to sit in the silence of the forest from time to time with a cup of aromatic freshly brewed coffee. You don’t have to think about the engine, because the mixer has a special shaft that rotates custom attachments.
Engraver
From time to time, a home craftsman has problems with surface treatment that are impossible to approach with universal equipment. The part may turn out to be fragile and impossible to clamp, or massive. It needs to be modified on site. From an old grinder you can make a tool for processing small surfaces with a flexible shaft. The result will be an analogue of a drill.
Materials required for production:
- a flexible shaft, which is purchased or selected from what is available;
- working tool holder;
- a pair of bearings with spherical rollers with a diameter of 228 mm;
- working tool for processing with a shank diameter of 1-3.5 mm.
The presence of a flexible shaft will expand the functionality of the tool. With its help you will be able to get into the most hidden corners of the part and reduce the load on your hands.
Almost all of the master’s household supplies can be used as tools:
- Drill. With its help, the tool will turn into a small drill or drill.
- Milling cutter. Using the design of cutters, you can process flat models, recesses of different shapes and depths.
- Cutting discs for processing thin materials.
- Metal and felt brushes for grinding and polishing surfaces.
- Abrasive tool with heads of various shapes.
- Tool for writing inscriptions.
Cutters can be made from broken drills, sharpened at the required angle.
Making a miter box
what can be made from a burnt grinder. But if the tool has not failed, and you want to expand the range of tasks it performs, you can make a miter box. To do this, the tabletop is made rotating. This will allow you to cut a baguette, plinth or profile from different materials at a certain angle.
The tabletop is installed at an angle, the corresponding disk is mounted, then cutting is carried out, which turns into pleasure. Using such a homemade machine, you can cut paving slabs diagonally, thereby diversifying the ways of laying them.
Fraser
An indispensable tool for woodworking. Professional models are expensive, and the router itself is not needed very often. But from a grinder you can make a machine that is not inferior to factory ones. To do this you need:
Buy a drill chuck with M14 thread or make it yourself. Install it on the angle grinder instead of the clamping nuts. Assemble the base
It is important that the tool must be adjustable in height - two guides with the ability to fix the grinder.
For materials, we choose what is at hand. A plywood machine is suitable for working with wood. The base plane should be as flat as possible, otherwise it will be difficult to achieve good quality processing.
If you need to make a collet chuck for cutters from a magazine, then this is also possible. Craftsmen often use homemade equipment made of copper and bronze.
Self-refinement to a cutting machine
The simplest homemade machine is a machine made from a small angle grinder. The work will be accompanied by a minimum of costs, and manipulations will take a few hours. The exit structure will be a long metal pipe that serves as a handle and frame.
A metal transverse strip with two holes for fastening the tool is welded to one of the ends. On the same side, the pipe is fixed to a piece of angle on a movable shaft. The first one can be fixed to the desktop or to the floor in the workroom. If you are faced with the question of what can be made from an angle grinder, you can use a cutting machine using the described algorithm. According to it, on the opposite side of the fastening it is necessary to fix a spring, which will ensure the return of the structure to its original position. After completing this stage, you can use your homemade product. You just need to install the device correctly.
This version of the machine is the simplest solution for metal processing, while complex work will require precision, so the design for solving such problems must be made more stable, which means the work will have to be approached more thoroughly.
Homemade lawn mower
Instead of a new lawn mower, it is completely possible to assemble the model with your own hands - for this you need an angle grinder and straight arms.
This type of lawn mower is the least powerful and has the smallest dimensions. Almost always, instead of knives, special fishing lines are installed on it to cut the grass - this is shown in the photo. A grinder mower is convenient because the tool can be simply removed and used for its intended purpose. How to make a lawn mower from an angle grinder is described here.
So how to create such a crusher?
- We make a small hole in the existing sheet so that we can fill it with what we need.
- Secure the grinder with bolts
You need 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 thresher
The easiest and most necessary method of creating miracles. Currently Bulgarian
is an irreplaceable thing in the household and for every master. There are many cool ideas, but the best are described in this article, which are developed and easy to use, the main thing is desire and everything is understandable.
Manufacturing a machine with a frame
You can also make a cutting machine from a grinder To do this, you should prepare the following tools and materials:
- profile pipe;
- steel corner;
- Metal sheet;
- welding machine;
- drill;
- channel;
- bearings;
- shaft;
- pipe;
- spring;
- relay pedal.
READ The better way to lubricate the grinder gearbox
If desired, the sheet of metal that goes on the platform can be replaced with chipboard. The stove will be an easier option. There must be several bearings, they must be the same. If you think about it, welding can be replaced with strong bolts, which is what you need a drill for. This option will allow you to disassemble the machine if necessary.
For a screwdriver
The screwdriver used by the author of the following video already has to work under extreme loads when cutting threads on M8. The use of a reduction gear from an angle grinder increases the amount of torque and allows you to cut threads in more comfortable conditions. Here we use a burnt grinder , where the rotor is cut to a length that at the same time allows us to securely fasten the end of the cut shaft in the screwdriver chuck and fit the plastic body of the grinder tightly onto it. For a more thorough connection, the screwdriver is attached to the body of the angle grinder with fasteners, while the gearbox bearing of the angle grinder fits into its seat. Drilling and cutting threads with tooling prepared for such work does not require any additional effort.
Here's what you can make from a windshield wiper motor and an angle grinder gearbox!
Sliding gate drive
The following video shows one of the options for driving sliding gates based on a gearbox from a burnt angle grinder and an old screwdriver. The drive is equipped with an automatic device for controlling the opening/closing of the gate. The chain drive with a drive sprocket on the gearbox spindle operates at high speeds to perform the gate control function, therefore creating increased noise during operation.
Pendulum saw + (Video)
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. A frame is located on a movable bushing, and an angle grinder is mounted on it. The counterweight can be any weight in combination with a return spring.
An angle grinder, simply a “grinder”, has three main areas of use.
- Cutting hard materials;
- Grinding with abrasives;
- Cleaning surfaces with brushes.
The technology involves holding the angle grinder with your hands while working.
However, for convenience and expanding the capabilities of the tool, many devices have been invented. Let's take a brief overview:
DIY homemade gearbox from an angle grinder
worth it)) and another friend gave me a powerful grinder, but they tore out the gearbox in common with Uncle Vasya, a fucking turner. We connected two Anchors and got this miracle. in general, from the saw frame there is a piece of an armature and a gearbox. from the Bulgarian, practically weighing the Bulgarian without a gearbox. nags wow so cool
Various accessories for angle grinders allow you to expand the functionality of the tool and make it convenient.
- Grain crusher.
- Lathe.
- Knife sharpener.
- Powerful drill.
- Tape Grinder.
- Assembly saw.
- Home mini sawmill.
- Milling machine.
boat motor
If you are an avid fisherman with a PVC boat and have only used oars until now, you should think about making an inexpensive propulsion unit. Gasoline engines are expensive, consume a lot of resources, and make a lot of noise. They are good for fast and long hikes. If you need to go out into the middle of the lake or check supplies, you can get by with consumables from an angle grinder. For a non-working tool, you will need an angular gearbox.
To mount the engine, we make a transom from plywood, a hinge, and 20*20 mm pipes. You will also need a pipe to attach the leg, screw and attachments. The screw, with low engine power, is cut out of 4 mm steel and bent. For the propeller you will need a battery and a 12 V motor. The battery capacity is calculated depending on the engine power and operating time. It is better to take a spare battery.
Drilling machine from an engine from a washing machine and a gearbox from an angle grinder
Materials and tools used by the author:
List of materials: - motor from a washing machine 650W / 1350 rpm; - gearbox from a 180 angle grinder; - angle; - round pipes; - sheet steel; - bolts and nuts; - springs; - switch; - cable with good insulation.
Drilling machine manufacturing process:
Step one. Refinement of the gearbox For the machine you will need a gearbox from a 180 grinder; it lowers the engine speed more than a gearbox from a 125 grinder, as a result, we get a higher torque, and the axle in such a gearbox is thicker. The author, using a grinder, cuts off a piece of the anchor and knocks the remains of the anchor off the axis. You will also need to cut off a piece from the body of the angle grinder in order to screw this part with a seat for the bearing to the gearbox. If there is no such part, you can weld it yourself from sheet steel, using a piece of pipe as a clip.
Step three. BaseWe make a base for the drilling machine; it must be as strong as possible so that the entire structure does not fall. You can use a piece of a suitable channel as a base. If there is no channel, it can be welded from thick sheet steel. We weld the ears to the base to secure the machine to the base with bolts.
READ How to make a circular saw from an angle grinder
We also weld 4 racks to the base; these can be pipes or steel rods. First, we insert the rods into the carriage, and then we grab them to the base. This is the only way to install the racks correctly.
Step seven. Final touches and tests We install a drill chuck on the gearbox shaft to screw the chuck, you can weld a nut for an angle grinder to it or cut a thread directly in the chuck.
We paint the frame so it doesn't rust, now the machine looks great. We install a convenient switch to quickly turn off the machine if something happens. The machine is ready, the author put a huge drill in the chuck and uses his monster to drill everything in a row, from wooden beams to thick sheet steel.

Sander
Converting a broken grinder into a grinding or polishing machine is not difficult. You can adjust the number of revolutions using a dimmer (lighting regulator) if the power of the tool is low. Otherwise, a laboratory autotransformer is used to regulate the voltage.
A grinder with a diameter of 125 mm can be converted by removing the protection and fastening nut. A support plate with Velcro is installed in their place. Such a tool is sold in any tool store. A grinding disc of a suitable configuration is attached to it. The discs on the other side have a felt lining. Thus, the new tool will be able to sand wooden boards and bars. A felt surface, in the presence of an abrasive paste, is used to polish car headlights and bodies. It is better not to use a tool with a power of less than 1 kW in professional activities. Grinding gives a greater load than trimming, so low-power machines can literally burn out at work.
Grain or plant grinder
If you live in a country house and raise any livestock, then an electromechanical grain crusher will be useful for preparing food. It is not intended for large volumes, but it can cope with medium volumes.
To create it you will need a container - it could be an old saucepan or tank, it all depends on the required size and power of the grinder. The cover should be remade so that the working shaft of the angle grinder is connected to the axis on which the cutting knives of the crusher are located. It is also necessary to provide a window for pouring portions of grain - it must be equipped with a door.
- Frame on the base of the lid. It is needed to strengthen the device; the racks can be attached with rivets or bolts.
- An axis that passes through the upper and lower bearing. It reduces the load on the electric motor.
- Knives for crushing grain. They are also fixed on the axis of the device.
Other options are also possible - with a lower position of the knife and a tank on top.
Gorgeous HANDMADE from a broken grinder!!! Nobody has seen anything like this before!!!
Or a small structure where the angle grinder shaft passes through the bottom of the container.
Outside the city, it is possible to assemble a dry grass shredder that will help deal with garbage on the site.
When making homemade machines, it is important to follow safety precautions. This is especially true for parts and electrical wiring rotating at high speed. It is recommended to equip machines with protective covers and securely fasten rotating elements: chucks and disks.
Do not also forget that the grinder engine needs periodic rest. It should not be left to work under load for a long time.
The grinder allows you to assemble many useful devices for your home, garage and countryside. Each of them can significantly facilitate routine operations.
Restoring a grinding disc for an angle grinder
As we can see in the photo above, the edge of the disk is very worn and the quality of grinding has deteriorated, and in order to restore it, you need to take an electric sharpener and simultaneously run the sharpener and the disk to grind off the worn part.
This procedure can be performed up to two times on one disk, I checked it personally. After this, the quality of grinding increases. But if the petals of the grinding disc have fallen off, as in the photo below, then you shouldn’t throw away such a disc either.
The first step is to independently separate all the remaining petals from the disk and clean the base.
Next, take a regular piece of sandpaper
(ATTENTION! Do not use paper-based sandpaper, only rag sandpaper, since paper paper cannot withstand high speeds)
, apply the disc, trace it and cut it out with scissors. After that, we make a hole in the middle, apply the emery wheel to the grinding disc and place it on the angle grinder.
After this, you can completely calmly clean the necessary parts and the quality will not be inferior to a regular grinding disc.
Homemade products, what you can do with your own hands, where to adapt the gearbox
A significant number of mechanisms operate at shaft speeds after the grinder gearbox. Therefore, there are more options for using an angle grinder gearbox for the operation of other devices. Together with non-standard ways of using an entire grinder for homemade products, masters of technical creativity create interesting compositions. Some are presented by the authors in specially filmed videos.
