Burs

Long-Life Burs

A titanium aluminum nitride (TiAlN) coating provides heat and wear resistance for longer life.

Extra-Long Burs

Extend your reach with these 3" to 7¼" long burs.

Flexible-Shank Burs

Reach around barriers to cut, grind, shape, and remove sharp edges in hard-to-access spots.

Burs for Soft Metals and Plastics

Specially spaced flutes quickly remove materials such as aluminum, brass, bronze, and plastics without clogging.

Burs for Masonry, Ceramics, and Composites

Diamond-cut teeth effectively cut hard materials.

Burs for Wood and Rubber

Pointed teeth cut wood and rubber quickly without clogging.

Grinding Bits

Long-Life Grinding Bits for Nonmetals

The diamond abrasive in these bits is extremely hard and lasts longer than tungsten carbide. For longer tool life and improved finish, use a water- or oil-soluble mist or coolant.

Grinding Bits for Nonmetals

Almost as hard as diamond, these tungsten carbide bits cut through nonmetals without generating heat.

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.

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.

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.

High-Performance Grinding Bits for Metals

Made of ceramic alumina, 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.

Grinding Bits for Stainless Steel

Bits are specially formulated to stay cool during grinding, so they won’t mar or discolor stainless steel.

Cotton-Laminate Grinding Bits for Metals

Made of cotton fiber layers embedded with aluminum-oxide grains, these bits grind and finish in one step.

Miniature Multipurpose Grinding Bits

Grind a variety of materials, from metal to ceramic and plastic, in precise, detailed jobs.
