Silicon carbide sanding belts are abrasive belts used for sanding and finishing various materials. They are made with a backing material, typically cloth or paper, and coated with silicon carbide abrasive grains. Silicon carbide is a hard and sharp mineral known for its excellent cutting ability and durability. Sanding belts with silicon carbide abrasives are commonly used in woodworking, metalworking, and other industries where aggressive material removal and smooth surface finish are required. They are available in various grit sizes, which determine the coarseness or fineness of the abrasive particles on the belt. Silicon Carbide provides an even cut and works great for wet or dry sanding and polishing marble, granite, glass, rubber, fiberglass, automotive paint removal, and finish removal.
