787C Fibre Discs, Ceramic, 4 in Dia, 80+ Grit

Rapidly cuts hard to grind metals like stainless steel and high nickel alloys. Premium mineral excels at heavyweight applications such as weld grinding, beveling, and edge chamfering. 3M™ Precision Shaped Grain yields higher cut rates and cooler cut while completing more parts per disc than conventional fibre discs. Grinding aid minimizes grinding temperatures for heat-sensitive alloys. Stiff fiber backing and strong resin bond provide durability and tear-resistance.
