Flap Discs are coated abrasives that are versatile at grinding and finishing. Flap Discs consist of three main components: Backing plate, adhesive and abrasive cloth flaps. These strong yet flexible cloth backed flaps are then overlapped and glued to the backing plate. Flap discs uses can range from heavy stock removal to cleaning/finishing work.
