DeWALT DABP4SR58 Medium Turbo Backing Pad, 4-1/2 in Dia, 5/8-11 Arbor/Shank, Fiber/Resin

These backing pads have a turbo design that keeps the fiber resin disc cool. The firm (rigid) backing pad is ideal for demanding applications that require more pressure when grinding. These are suitable for high-stock removal such as chamfering, beveling and thick weld blending. The medium (semi-rigid) backing pad is suitable for applications that need flexibility such as weld blending, burr and oxidation removal and finishing.
