The grinder is the most “folk” instrument. And not only because it allows you to perform a wide range of tasks: from cutting metal to sanding wood.
An angle grinder is still very often used for making various homemade devices.
In some cases, the grinder acts as a drive (that is, it is used entirely). In others, only its spare parts are required.
If you don’t have a hand router, you can easily make it from a regular grinder. Read a detailed review of the homemade product here .
In this review, we want to share with you the coolest devices made from an angle grinder. Sit back, it will be interesting.
Machine for cutting circles from metal
Usually, cutting machines are made on the basis of a grinder. There are a dime a dozen such homemade products on the Internet. There are also many ideas on this topic on our website, and we will not repeat ourselves.
But a machine for cutting circles out of sheet metal is a really cool idea.
With the help of a homemade device you can cut circles of different diameters. Fast and easy. In general, this homemade product definitely deserves your attention.
Basic tools and materials
Homemade does not imply changing the design of the angle grinder itself. To make a homemade device from a grinder, use various cutting tools:
- saw;
- jigsaw;
- hacksaw for metal.
If you need to fix the grinder to the surface, plastic clamps or ties are suitable. When drawing up drawings and markings, you cannot do without a pencil, ruler and meter. If a master wants to make a wall chaser or cultivator, then he will need a different cutting disc and different attachments.
Important! Other materials may also be required, for example, sandpaper, if you want to assemble the grinder. The selection of units is individual and depends on the device to be assembled.
Homemade small branch shredder
The problem of recycling small branches is relevant for many summer residents and owners of private houses.
Factory shredders are not a cheap pleasure (not everyone is ready to spend money on purchasing such a unit).
But why pay for anything at all when you can do it yourself?
You can make a homemade shredder for small branches yourself, using a grinder and an old (non-working) motor as a basis.

Good day to all.
Today I will show you some ideas of what you can do from an old grinder. Any master or simply someone who does men's household chores himself has encountered this - the grinder has broken down for some reason and cannot perform the functions of an angle grinder. In fact, either the gearbox or the electric motor can break. Let's consider the first case when the gearbox has failed, but the motor is working. 1- Let’s make an engraver out of an angle grinder with our own hands. All you need to do is disassemble the gearbox and cut off everything that is no longer needed. In the end, you should end up with a thread similar to this.
Next, we buy an ER11 collet chuck and install it on the angle grinder shaft, having previously removed the gear that rotated the gearbox.
The design should look like this. The result is a fairly powerful engraving machine, considering that the power of an angle grinder is rarely below 500 watts, and the engravers sold in stores are usually from 130 to 200 watts.
2-now, let’s still consider the case that the angle grinder did not fail, but simply became unnecessary, or the gearbox developed a large backlash and it became impossible for it to saw. Let's make an engraver out of it first. This time you will need to purchase a flexible shaft from the nearest electrical equipment store. They are not expensive. This is what he looks like.
Mini grinding machine (grinder for workshop)
For high-quality processing of wooden and metal workpieces, it is convenient to use belt sanding machines (more popularly known as grinders).
A grinder driven by an angle grinder is a rather interesting and useful homemade product.
The design of the homemade product is light and compact, and accordingly, it does not take up much space on the desktop and does not cause trouble during transportation.
At the same time, the grinding machine copes well with its task - grinding workpieces.
What can you make from an old grinder?
If the grinder is unburnt and the engine is intact, then you can use it as a sander for wooden floors. The only thing left to do is a wide round casing, under which to place an abrasive wheel for grinding the floor.
In the event that the grinder’s engine is burnt out, you will need to connect a screwdriver or electric drill through the gearbox. In this case, the angle grinder gearbox will serve as an adapter.
Do you need a mounting saw with vertical and horizontal clamps (read the website)? It’s not a problem if there is an old unnecessary grinder left on the farm. It is enough just to build such a fastener in the form of a machine, and the clamping saw is ready.
Please note that the grinder can be used in this case, both for its intended purpose and to transmit torque to the rollers on which the abrasive belt will be located. The stand for the grinder in this case is assembled from a profile pipe, and the power tool itself is attached through a hole in the rolled metal.
In this case, it is important to ensure that the tube for fixing the grinder is movable, and at the bottom there is a stopper or a special release spring. It goes without saying that when performing work with an angle grinder, you must follow safety rules, and under no circumstances take risks using this tool without a protective casing.
Homemade grain crusher (for those in the know)
Those people who keep various domestic animals have to buy food in the form of crushed corn or cereal grains.
However, crushed raw materials are more expensive. And it is not profitable to buy it. To save money, you need to grind the grains yourself.
And this is exactly why our homemade grinder comes in handy - a tabletop grain crusher .
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:
Machine for quickly stripping rusty pipes
The grinder, of course, is intended for stripping metal of rust and paint - just install a cord brush or other abrasive attachment, after which you can start working.
But you can’t handle large volumes this way. Your arms will get tired quickly. If you need to clean a lot of rusty pipes, it is easier to use a homemade machine made from an angle grinder.
With the help of this homemade product, you can quickly and without straining yourself clean both round and profile pipes. This is a really cool homemade product - take note of the idea.

Ask a Question
Where can you use an angle grinder with a burnt out engine?
An angle grinder's anchor, if it cannot be restored, for example, when the lamellas or windings on it are damaged, can be used to make an adapter attachment for a screwdriver, drill, etc.
In principle, for this the anchor has everything we need, namely:
- Smooth surface and round shape;
- A rod that could be caught on;
- Slots for installing sanding belt.
The principle of operation of such a drill attachment is very simple.
You take it and install it in the chuck, after which you begin to process various workpieces with the nozzle. They can be made from materials such as wood, plastics, metal and even glass and ceramics.
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.
Motorized bicycle
Making a self-propelled bicycle is easier than it seems. You don't even have to disassemble the grinder. You will need an inverter from 12V to 220V, lithium batteries, and a button with a power regulator. The essence of the mover:
- The shaft will transmit torque directly to the tire. For this purpose, a bushing is made with roughness for better engagement.
- We attach the machine to the frame.
- To press the bushing, we use a cable similar to a brake handle. This will make it possible to turn on the engine not constantly, but to use it as an auxiliary one.
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.
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.
