Long-Life Rubber-CushionedAbrasive Grinding Bits for Metals. A diamond abrasive that's bonded to a rubber cushioning makes these bits last 10 to 20 times longer than rubber-cushioned bits without diamond. Because they're cushioned during grinding, these bits produce a smoother surface texture than other bits with similar grits.
