In the manufacture of high-quality flexible abrasive material consisting of a fabric base on which a layer of calcined aluminum oxide is applied. This abrasive has harder particles than ordinary aluminum oxide - Corundum, which allows you to increase speed treated surface up to five times. The filling of the disc is up to 96 petals with an angle of inclination of 10 degrees, which allows you to increase the efficiency of the circle and its wear resistance by several times. Designed for processing metal and stainless steel. For angle grinders. Landing diameter 22.2 mm.
