They c onsist of a thin layer of abrasive adhered to fiber, paper, cloth or rubber. Coated discs are normally used on angle grinders. Type 27 flap discs are less aggressive and are used primarily on flat surfaces for grinding a smoother finish. More durable than aluminum oxide, zirconia-alumina is best for medium- to heavy-material removal. The material grains constantly fracture to produce new sharp edges. Commonly used on carbon steels, aerospace alloys, nickel alloys, aluminum, cast iron, forgings and some stainless steels Type-R discs feature roll-on/off fasteners.
