Flap discs have a design suited for right-angle grinder applications. They provide aggressive stock removal or precise blending and finishing depending on the operator\'s needs. In general, flap discs require coarser grit for initial work piece shaping and stock removal and finer grit for refinements such as blending, finishing and repairs.
