Tungsten carbide - Wikipedia
Sintered tungsten carbide - cobalt cutting tools are very abrasion resistant and can also withstand higher temperatures than standard high-speed steel (HSS) tools. Carbide cutting surfaces are often used for machining through materials such as carbon steel or stainless steel, and in appliions where steel tools would wear quickly, such as high-quantity and high-precision production.
