3M - 2" Wide x 72" OAL, 40 Grit, Zirconia Alumina Abrasive Belt - Zirconia Alumina, Coarse, Coated, Series 577F

Coated abrasives can be used from grinding to polishing for most applications. They consist of a thin layer of abrasive adhered to fiber, paper, cloth or rubber.

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.
