Superior Abrasives - 120 Grit, 2" Disc Diam, Zirconia Alumina Flap Disc - Plastic Backing, Quick Change Type R Attaching System, Coated

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-R discs feature roll-on/off fasteners.
