An abrasive band is a cylindrical tool made of abrasive material such as sandpaper, used for sanding, grinding, or polishing surfaces. It is usually made by bonding abrasive particles to a flexible backing material, which is then formed into a cylinder. Abrasive bands are commonly used in industries such as metalworking, woodworking, and jewelry making. They are also used in dental and medical applications for grinding, polishing, and shaping teeth and other dental materials.
