Long-Life Grinding Bits for Metals

Similar to diamond, boron nitride is harder than aluminum oxide and lasts longer. Bits are also known as jig grinding pins and mandrels.

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.
