Rubber-Cushioned Abrasive Grinding Bit Sets for Metals
 |
The bits in this set have rubber blended into the abrasive, which cushions during grinding to produce a smooth to extra-smooth surface texture.
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.
Aluminum oxide bits are for grinding hard metals.
Silicon carbide bits are for grinding soft metals.
