These belts last at least 50% longer and sand faster than standard ceramic alumina belts. The specially engineered grit stays cool while cutting, which prevents dulling. It's sharp and dense enough to shape hard metals such as stainless steel, nickel, and cast iron. Ceramic alumina grit continually fractures to produce new, sharp cutting edges. It sands faster and lasts longer than aluminum oxide but requires more force to abrade properly. A slick coating on these belts prevents debris from accumulating on the abrasive surface and keeps operating temperatures low. They also resist deterioration when used with water or cutting fluids.
