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. Also known as mounted points and die grinder bits.. Head diameter is measured at …
