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.

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 for steel are aluminum oxide, which is the most common abrasive used in grinding metal.
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.

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.

Arbors for Rubber-Cushioned Abrasive Grinding Bits
Thread rubber-cushioned grinding bits onto one of these arbors and switch between bits without removing the arbor from your tool. Arbors are also known as mandrels.
