Rubber-Cushioned Abrasive Grinding Bits for Metals
The abrasive grains in these bits are blended with rubber, which cushions during grinding to produce a smoother surface texture than other bits with similar grits. Bits are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
Bits for aluminum, brass, and bronze are silicon carbide, which cuts through soft metals without generating much heat or causing material buildup.
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.

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.

Long-Life Grinding Bits for Nonmetals
The diamond abrasive in these bits is extremely hard and lasts longer than tungsten carbide. For longer tool life and improved finish, use a water- or oil-soluble mist or coolant.
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.

Spiral-Wound Sanding Rolls
As the outer layer wears away, new abrasive is exposed. Also known as cartridge rolls. A shank adapter or tapered spindle with a shank is required (both sold separately). The most common abrasive material, aluminum oxide is hard enough to sand steel and wood. The diameter listed is for the large end of the roll.
Cone rolls are for use in holes. Unlike tapered rolls, they have a flat surface to allow for a more even finish within internal surfaces.
