High-Performance Grinding Bits for Metals
 |
Style 3 |
Made of aluminum oxide ceramic, these bits prevent material and heat buildup better than bits made of boron nitride and aluminum oxide when used on steel, stainless steel, iron, and titanium. They also last longer than boron nitride bits, so they’re the best choice for high-volume applications. 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 Metals
 |
Style 27 |
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
 |
Style 4 |
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.
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
 |
Style 2 |
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.

Grinding Bits for Stainless Steel
 |
Style 4 |
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.
