Norton - 3-1/2" Wide x 15-1/2" OAL, 36 Grit, Zirconia Alumina Abrasive Belt - Zirconia Alumina, Very Coarse, Coated, Y Weighted Cloth Backing, Series R824

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.
