Grinding Bits for Metals


Style 1	Style 2	Style 3	Style 6	Style 7	Style 8

Style 9	Style 14	Style 19	Style 21	Style 28

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.

High-Performance Grinding Bits for Metals


Style 2	Style 6	Style 7	Style 8

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.

Rubber-Cushioned Abrasive Grinding Bits for Metals


Style 1	Style 5

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.

Style

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

For Aluminum, For Brass, and For Bronze—Bits for aluminum, brass, and bronze are silicon carbide, which cuts through soft metals without generating much heat or causing material buildup.

Grinding Bits for Nonmetals


Style 5	Style 8

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.

Cotton-Laminate Grinding Bits for Metals

Style

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.
