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.
Aluminum oxide bits are for grinding hard metals.
Silicon carbide bits are for grinding soft metals.
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.

Miniature Multipurpose Grinding Bit Sets
Best for intricate, precise grinding jobs on metal, ceramic, and plastic, these sets include diamond abrasive bits with different head shapes. Their 3/32” diameter shank and small head make them great for tasks with fine details.
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.
