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 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.

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.

Long-Life Rubber-Cushioned Abrasive Grinding Bits for Metals
A diamond abrasive that's bonded to a rubber cushioning makes these bits last 10 to 20 times longer than rubber-cushioned bits without diamond. Because they’re cushioned during grinding, these bits produce a smoother surface texture than other bits with similar grits. 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 Stainless Steel
Bits are specially formulated to stay cool during grinding, so they won’t mar or discolor stainless steel. 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.

Cotton-Laminate Grinding Bits for Metals
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.
