Made with diamond abrasive, these bits are extremely hard and last longer than tungsten carbide. They have a small shank and head for precise and intricate jobs. To extend the life of these bits and improve their finish, use a water- or oil-soluble mist or coolant. They are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.

A keyless chuck (sold separately) connects these bits to rotary tools that accept a 1/8" shank diameter.

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.

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 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.

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.

Made of cotton fiber layers embedded with aluminum-oxide grains, these bits grind and finish in one step. They’re ideal for light deburring, blending, and finishing metal. These grinding bits remove material more efficiently than rubber-cushioned bits. While grinding, they resist the buildup of aluminum, brass, bronze, and other nonferrous metal. They’re 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.
