The abrasive grains in these bits are blended with rubber which cushions during grinding to produce a smoother surface texture than other bits with similar grits. Bits for steel are aluminum oxide which is the most common abrasive used in grinding metal. Bits for aluminum brass and bronze are silicon carbide which cuts through soft metals without generating much heat or causing material
