Grinding Bits for Metals
Made of aluminum oxide, these bits are well suited for use on most metals and materials that are not heat sensitive.
Bits are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
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.

Nylon Mesh Cushioned Sanding Bits
The abrasive-embedded mesh construction gives you more control over sanding pressure, creating finer and more consistent finishes in small, recessed, and hard-to-reach areas.
Coarse grade is for aggressive deburring and cleaning.
Medium grade is for deburring and polishing.
Fine grade is for light blending and finishing.
