Wood cutting wheel for angle grinder

How to properly change the disk on the angle grinder

Since the wheels for the angle grinder are consumables, then sooner or later they have to be replaced. They are attached to the spindle angle grinder with a clamping flange (nut) with a thread of M14. To unscrew it, a special horn wrench, which has pins on one side, must go in the package to the angle grinder.

So, to replace the tool on the angle grinder, follow these steps.

  • Turn off the power by unplugging the device from the socket.
  • Lock the spindle of the angle grinder with the button on the front of the housing. When the key is pressed the stopper enters the hole in the disk mounted in the gearbox and locks the spindle in the stationary position.
  • Insert the pins of the wrench into the holes on the clamping flange.
  • Hold the retainer with one hand and turn the wrench counterclockwise to the left with the other until the nut is loosened. Then it can be unscrewed without a spanner and removed from the shaft. In this case, the spindle of the angle grinder rotates clockwise. But which way to unscrew the nut if the shaft of your appliance rotates counterclockwise? Remember: always unscrew the clamping flange in the exact opposite direction to the shaft rotation.
  • The tool can now be changed by removing the old tool beforehand. If you notice that dirt has accumulated inside the housing, you should remove the bottom flange and use a steel brush to remove dirt from all surfaces.

After you have carried out the above steps, the tool change is considered complete.

Wood disc for angle grinder: varieties

Angle grinder or angle grinder allows the processing of various materials, including wood. If it is necessary to cut metal, resort to the use of an abrasive disc on the angle grinder.

If you decipher the abbreviation angle grinder, it is clear that the main purpose of the “angle grinder.

Are used mainly for primary (coarse) sanding of wood, when you want to smooth out the irregularities of the sample.

The name says it all. Such tips are used for finishing the final parts of wooden workpieces (cuts). Especially effective if you have to deal with angular (oblique) cuts.

The most commonly used sanding accessories for angle grinders.

The attachment on the angle grinder for wood brushing

Many craftsmen believe that the metal brushes are used to clean only steel products from rust, oxides. Contrary to this fact, products made of brass wire are popular in wood processing. Relatively low price, high service life, make the brush a direct competitor to abrasive nozzles.

The main purpose is to remove the paint coating from the material surface. It should be understood that the top layer of paint can be removed by applying temperature, the brush is used when working in hard-to-reach places.

It is also possible to perform wood brushing with an angle grinder with a brush. The process involves artificial aging of surfaces in the manufacture of unique interior products. Treated surface with soft wood particles, irregularities and temporary rings stand out.

The nuances of working with an angle grinder on wood

Professionals rarely use the angle grinder specifically to work with wood, for this there are special devices and tools. belt sander, electric saw, electric jigsaw. But in everyday life, if there is a need to perform woodworking works, buying a whole set of expensive tools is not reasonable, then the help comes to an angle grinder with wood sanding attachment.


angle grinder is not the most popular tool for sawing wood, as it is a material with a fibrous structure. With insufficient fixation and the slightest fluctuations and changes in the angle of cutting, the fibers are swelled, delaminated, formed chips, defects and dispersion of sawdust and chips.

The cutting attachment is justified only if the angle grinder is fixed as firmly as possible on the cutting table. With the angle grinder you can make only a rough, not precise cut, as it is impossible to organize all the conditions for precise work. rigidly fix the material, the tools and see the place of the cut.

Sanding and polishing

The angle grinder is excellent for sanding. The works are performed according to the following algorithm:

  • Preparation works. Initially a coarse grinding using the roughing head. It is in the form of a bowl with a twisted wire, located all around the perimeter (similar in appearance to a brush with metal bristles). At this stage, old layers of paint are removed from the board.
  • Preliminary (rough) sanding. Remove coating residues, protruding fibers and other defects from the surface of the material. Work is done using grinding wheels for angle grinder on wood. At this stage, the material is prepared for painting.
  • Final (fine) sanding. It is used for wood that will not be painted. For work, an angle grinder attachment is used for sanding wood with an abrasive of minimum grit. nulivki.
  • Polishing. Produced at low engine speeds, fabric wheels are used as an abrasive.

In order to maximize the convenience and quality of all processes, it is necessary to choose the right nozzle from the entire variety of their modifications.

Why it is difficult to process wood with the angle grinder

First of all, it should be noted that the high speed of the disk distinguishes the angle grinder from the circular saw. And even the presence of the compensatory ring, which comes complete with a disc, does not completely solve the problem. But if your angle grinder has adjustable speed, it partially makes it easier.

You can adjust the tool so that its speed corresponds to the speed of the circular saw, this will also reduce the injury hazard of the process

But the main difficulty is not that, but in the structure of the wood itself, which is often heterogeneous and knotted. In addition to multi-directional fibers, there is resin in the wood, possibly the presence of pellets or ingrown wire, which you immediately and did not notice. In general, wood is an unpredictable material. While working you may encounter an unexpected obstacle, and, as a consequence, a jerk that can knock the tool out of your hands and direct it along a dangerous vector.

If the disk encounters a piece of metal, the tooth can fly out of it, which, like a bullet, can also rush in an unpredictable direction. You will be lucky if there is a safety guard in the way

If you intend to saw with an angle grinder wood on the site, you will have to keep it in a horizontal position. This will make the grip uncomfortable and increase the risk of injury.

Important! It is categorically not recommended to saw wood with a tool that does not have adjustable speed and attachments not designed for this purpose.

Angle grinder a very wide range of tools in one class, called angle grinder (angle grinder). The device can have a huge power and work with a disc of 230 or more millimeters. Or distinguished by its compact size and modest abrasives of 115 mm.

The disadvantages of large and heavy tools are obvious: it is difficult to work for a long time. In addition, you need serious skills and experience to process wood accurately. It is elementary difficult for a beginner to control a massive and powerful angle grinder. However, when a large area of processing or the need to remove a significant amount of material such an angle grinder is very good.

Small angle grinder also has disadvantages. The ratio of its disc diameter to the size of the body does not allow you to process hard-to-reach places. In addition, it is difficult to select a large volume of material with such a tool because of low power and overheating.

Many masters for working with wood prefer an angle grinder with a disc diameter of 125 mm. This is explained quite simply:

  • in this class are represented angle grinders in a wide range of working powers;
  • it is easy to choose a tool with comfortable dimensions and weight;
  • There are many aids and appliances on the market that are designed for a standard 125 mm blade bore.

In addition, the average power angle grinder provides relative safety for beginners. It will not make you get tired quickly, allow you to more accurately control its movement, reduce the likelihood of rejects on valuable parts.

Angle grinder applications for cutting various materials, cutting and sanding wood

If you are trying to understand whether you can angle grinder to saw wood, then the answer to this question is unequivocal: you can. But many people will not do it, because they don’t want to.к. Too many injuries people receive precisely from the use of angle grinder as a saw on wood, which is properly referred to as angle grinder.

First of all, this is caused by its rather high rotation speed, for which most saw blades are simply not designed. But who pays attention to it, when it is necessary to do a job, and there is seemingly a suitable tool at hand, and there is also a compensator ring of the right size attached to the wood saw blade. Yes, and even remove the protective cover for the convenience of work, which you can not do.

But we are not going to tell about injuries, but to talk about what and how it is possible to work (including the cutting of the saw blade).ч. saw) wood with an angle grinder, but first. about the complexities of working with angle grinder is wood.

What to look for when selecting a wood saw blade?

The key features to focus on when choosing a saw blade for an angle grinder are as follows:

  • Outer diameter of accessories.The size of the wheel largely depends on the power of the angle grinder and the type of work performed. The 12.5 cm blade is best suited for wood. Larger diameter increases productivity, but requires professionalism and increased safety precautions.
  • Inside diameter (bore).For angle grinders it is standard. 22 mm. Otherwise, discs can be mounted through special adapter rings. Some models can be equipped with this accessory.
  • Type of disc.Monolithic tooling is characterized by low cost, but requires periodical re-training of teeth and sharpening. The more reliable carbide saw blades do not need frequent maintenance and produce a clean cut at any speed.
  • Number of teeth.A cross-cutting cut requires discs with a high number of cutters. 60-90. Accordingly, a longitudinal cut is of higher quality when using models with a small number of teeth.
  • Rotation speed.High-speed discs are suitable for work with hard or dense wood. Low speed tooling ideal for soft and tough wood.
