Tungsten Carbide Bit

Tungsten carbide bit is a type of tool attachment made out of a specialized metal alloy. Carbide is properly called tungsten carbide and is a specific combination of those two materials. The actual definition of tool tungsten carbide bit varies slightly, but it is always the specific part of a tool that contacts the worked material. A tungsten carbide bit is much harder than steel, but it is also more brittle. As a result, many larger bits are made of cemented carbide or steel with a brazed carbide tip. And that's why tungsten carbide is often combined with metallic cobalt to create cemented carbide.
