Is it not a secret that an electric drill is a universal instrument, which is successfully used for cutting various materials, grinding surfaces, as well as for polishing different surfaces. Today industry offers a number of nozzles for drills facilitating the working process in the processing of wood, metal, stone and concrete.The abrasive materials for grinding wheels are usually the following: electrocorundum, silicon carbide (black and green), boron carbide and diamonds. The wheels from green silicon carbide are used for finishing metalworking tools, hard alloys, ceramics, stone and correcting wheels from other abrasive materials. Black silicon carbide is used for grinding hard alloys, cast iron, non-ferrous metals, glass, plastics, leather and rubber. The pastes made of silicon carbide are necessary in the process of finishing works. Silicon carbide abrasive materials are used in electrical, metallurgical and refractory industries. Such materials are also added to aerodrome coatings, stairs, tiles and other products.
