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.

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.

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.

Similar to diamond, boron nitride is harder than aluminum oxide and lasts longer. Bits are also known as jig grinding pins and mandrels.

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

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

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.

The diamond abrasive in these bits is extremely hard and can grind metal, ceramic, and plastic.

Best for intricate, precise grinding jobs on metal, ceramic, and plastic, these sets include diamond abrasive bits with different head shapes.
