Abrasive wheel selection

If you are a grinder, you will no doubt need abrasives. The most popular consumables for this tool are grinding, cutting and grinding wheels.

There are various classifications of materials. Some of them are used to cut various materials, while others can be used for cleaning, grinding, polishing or removing a layer of corrosion. Using products of certain types, it is possible to successfully process surfaces of various types: concrete, wood, natural stone and others. We will consider some recommendations on abrasive wheel selection.

Where to start the choice?

At the very beginning, it is important to carefully read the inscription on the abrasive material. All circles indicate the most diverse characteristics, thanks to which you can get important information. On products that meet international standards, the marking is indicated, thanks to which you can get information about the materials that were used.

On the image you can see illustrations of natural stone, tile, concrete, metal and others. On some circles there are images of gloves, a respirator and other protective equipment that are recommended for use when working with them. Thanks to certain designations, you can find out that you need to use cooling when working with a circle. Reinforcement marking is used for hand tools. Abrasives intended for stationary machines are marked «FROM». This indicator will be useful when choosing circles. On the consumables, their dimensions are applied: the diameter of the landing hole, the diameter of the circle, its thickness and maximum rotation speed.

Important information that can be obtained from the labels

On abrasive wheels, a description of the material that can be processed with it is applied. Many manufacturers on the metal part of the product indicate the time during which the abrasive can be used. Be sure to rate this indicator. Sometimes on sale you can find circles at scanty prices, this is due to the expiring time of their use. When working with such abrasive products, builders put their health at risk and the health of those around them who work nearby.

When choosing an abrasive product, it is important to consider the permissible speed of its rotation. It should always exceed this figure for a grinder. In the implementation, you can find circles with a red stripe. So can be designated petal, stripping, grinding, diamond and other varieties of circles. In the middle of the product there may be a color bar; you can find out about the maximum revolutions of a circle by its color.

If the strip is yellow, then the maximum rotation speed of the circle is 63 m / s, for the red strip this characteristic is 80 m / s, and for the green one – 100 m / s.

We analyze other characteristics

There may be various signs on the circles. So, thanks to the letter F, you can get information about the grain size that is used to make abrasives, using other letters of the Latin alphabet will allow you to get information about the hardness of the material. Special connecting ligaments allow you to connect the material of the circle. Such bundles can be of the following varieties: ceramic – V, bakelite with increased strength – BF, bakelite – B, bakelite with graphite filling B4. The material used to create the circles falls under the marking: electrocorundum is indicated by the letter A, elbor – B, silicon carbide – C, and diamond – D. These are the most popular types of abrasives.
