Grinding Bits for Nonmetals
Almost as hard as diamond, these tungsten carbide bits cut through nonmetals without generating heat.
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.

Grinding Bit Sets for Nonmetals
Best for grinding composites, fiberglass, plaster, plastic, rubber, and wood without generating heat, these sets include a selection of our most popular tungsten carbide bits. The bits are also known as mounted points and die grinder bits.
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.
