Grinding Bits

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.

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 Stainless Steel

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

Grinding Bit Sets for Metals

Each set contains a selection of our most popular grinding bits.

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.

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 Grinding Bits for Metals

The small 3/32" diameter shank and small head makes these bits good for precise and intricate jobs.

Grinding Bits for Nonmetals

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

Sanding Bits, Drums, and Sleeves

Replaceable-Cap Sanding Bits

Slip a cap onto the head of a shank and sand small, recessed, and hard-to-reach areas.

Replaceable-Cap Sanding Bits for
Stainless Steel and Hard Metals

The ceramic alumina grit in these bits is sharp and dense enough to shape hard metals such as stainless steel, nickel, and cast iron without dulling quickly.

Replaceable-Cap Sanding
Bits for Countersunk Holes

Choose a bit with the same angle as your countersink to debur the inside of the hole.

Spiral-Wound Sanding Rolls

As the outer layer wears away, new abrasive is exposed.

Spiral-Wound Sanding Rolls with Shank

The secure bond of the roll to the integrated shank prevents loosening from vibration while sanding, resulting in a smooth finish.

Long-Life Spiral-Wound Sanding Rolls

The premium abrasive stays sharp longer.

Long-Life Spiral-Wound Sanding Rolls with Shank

Change your sanding rolls less often and produce a more consistent finish compared to standard sanding rolls.

Spiral-Wound Sanding Rolls for
Stainless Steel and Hard Metals

Coated with ceramic alumina abrasive, these rolls are sharp and dense enough to shape hard metals such as stainless steel, nickel, and cast iron without dulling quickly.

Sanding Pads for Internal and Irregular Surfaces

Sand inside pipes, tubes, and hard to reach corners with these pads.

Sanding Pads for Internal and Irregular
Surfaces on Stainless Steel and Hard Metals

The ceramic alumina abrasive on these pads is sharp and dense enough to shape hard metals such as stainless steel, nickel, and iron without dulling quickly.
