Carbide burrs (sometimes spelled burs) are tools used for deburring most hard materials like ceramics, stone, steel, aluminum, plastics and hardwood. They provide precision, and can also be used in cutting, shaping, grinding and chamfering hard materials. Tungsten carbide, historically called Wolfram, after its discoverer Peter Woulfe, is usually referred to simply as carbide; it is also known by the names cemented carbide, solid carbide, hardmetal and occasionally as tungsten. Tools, such as burrs, made from carbide withstand higher temperatures and maintain a sharper cutting edge than high strength steel.
There are a wide array of burrs dependent on the task, derived from 13 common burr shapes, and seven common burr flute styles. The shank is the mount of the burr that fits into the rotary tool, grinder, etc.
Carbide burrs typically come in three standard flute styles: single, double and nonferrous. However, there are several other varieties of flute styles, including fine, coarse, diamond, chip breakers, foundry cuts, Omega Cut and more.
