- Coated abrasives can be used for most applications, from grinding to polishing. They consist of a thin layer of abrasive adhered to fiber, paper, cloth or rubber. Coated discs are normally used on angle grinders.|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 27 flap discs are less aggressive and are used primarily on flat surfaces for grinding a smoother finish.
