Miniature Rubber-Cushioned Abrasive Grinding Bits for Metals
Produce a smooth surface on precise, intricate grinding jobs. These bits are cushioned by rubber, so they create a smoother finish than other bits with similar grits. Made with a diamond abrasive, they last 10 to 20 times longer than rubber-cushioned bits without diamond. Their 3/32" diameter shank and small head allow them to get into intricate spots. Head diameter is measured at the widest point.
A keyless chuck (sold separately) connects these bits to rotary tools that accept a 1/8" shank diameter.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
