Miniature Rubber-Cushioned Abrasive Grinding Bits for Metals
Produce a smooth surface on precise, intricate grinding jobs. These bits are cushioned by rubber, so they create a smoother finish than other bits with similar grits. Made with a diamond abrasive, they last 10 to 20 times longer than rubber-cushioned bits without diamond. Their 3/32" diameter shank and small head allow them to get into intricate spots. 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.

Miniature Grinding Bits for Metals
The small 3/32" diameter shank and small head makes these bits good for precise and intricate jobs.
Bits are aluminum oxide, which is the most common abrasive used in grinding metal. They 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.

Miniature Long-Life Grinding Bits for Nonmetals
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.
