The PFERD CC-GRIND®-SOLID is a 7-inch ceramic grinding disc for steel, designed for use with an angle grinder featuring a 5/8"-11 arbor. Its highly aggressive abrasive delivers fast results and a finer surface finish than conventional grinding wheels, while the layered fiberglass backing provides comparable durability and safety. Compared with a conventional grinding wheel, it reduces noise and vibration by 50% and dust by 80%.
