Overview of cleaning and grinding wheels on the grinder

To remove paint from walls or metal surfaces, as well as to remove rust, it is necessary to make a lot of effort and spend a lot of time. Therefore, it is sometimes impossible to do without the use of power tools. As a device to facilitate the process, you can use an angle grinder (grinder) with special cleaning nozzles.

Paint strippers

Old paint often has to be removed either from the walls or from metal surfaces. In each case, different types of nozzles for grinders are used.

From metal surfaces

For roughing works on metal, be it the removal of a layer of old paint or the removal of rust, masters use korshchetki. They look like a brush of metal twisted or non-twisted wire inserted into a metal cup, or a disk of the same wire.

From the masters who used the brushes for scraping metal, you can hear complaints that small pieces of wire fly away from the nozzle and dig into clothes.

Depending on what kind of roughing work you want to do, the thickness and rigidity of the brushes are selected. It is necessary to take into account the fact that the metal wire used in the brushes leaves scratches on the treated surface. Therefore, to remove the paint, for example, from the car body, it is better not to use them. They can be useful only to remove rust and paint from hard-to-reach places.

For metal-friendly roughing It is better to use special circles of carbide silicone fibers (XCS) - they are usually black. Also used for these purposes are more wear-resistant discs Clean and Strip. They are blue in color, have a similar structure, but consist of nylon threads.

This grinding wheel is available in 2 versions: for the drill and for the grinder. A distinctive feature of it from other types of nozzles for removing paint from metal is that it does not get clogged and does not cause metal damage in the form of scratches.He also successfully removes welding spatter, rust, various sealants and anti-corrosion coatings.

Clean and Strip circles have good wear resistance and can be used until completely erased.

Often used to remove paint from metal petal nozzles for the Bulgarian. They represent a disk with sandpaper glued on its plane in the form of petals.

For roughing the surface using nozzles with a large grain size. For finishing work, it is necessary to select a peeling disc with fine sandpaper. Although this emery disc quickly wears out and becomes clogged with the remnants of the discarded paint, it can be simply restored. How this is done can be understood from this video.

From the walls

First of all, to remove the paint from the wall, the masters try to use the wire brushes with a thick twisted wire (they were discussed above). This method is quite effective, but when roughing a lot of dust. Therefore, it is necessary to use protective equipment (glasses, respirator). It is also recommended to use a vacuum cleaner with a special nozzle that completely hides the wrist.

In addition to removing paint from walls, you can remove a layer of old plaster, primer or putty

To remove the painting from the concrete walls are also used cup nozzles. The grinder must be kept at an angle so that the layer of paint is removed, but the recess of the tool in the wall did not occur.

In addition to roughing work, this nozzle is also used for leveling surfaces, removing various nodules on the wall, for removing plaster, putty, etc.

Grinding wheels

This category of disks is intended for rough metal work. The sharpening disk can be used for cleaning welds, chamfering on cut metal parts, as well as for sharpening tools (drills, chisels, etc.) if there is no grinding machine nearby.

It is worth knowing that when installing such a disc, the revolutions on the grinder should be set to the minimum or not exceeding the values ​​indicated on the abrasive wheel.

As a rule, sharpening discs are more often used on small grinders, since it is more convenient to use them for metal stripping.

The grinding wheel can be distinguished from the cutting one in thickness (not less than 5 mm) and by the presence of a recess in the center for more convenient use of the planedisk for sharpening the tool.
