05/03/2021  Tungsten Carbide falls between 8.5 and 9.0 on Moh's hardness scale, making it almost as hard as diamond. In order to polish or finish tungsten carbide, a diamond covered tool must be used because any other metal or mineral would not be able to withstand its hardness. Only a diamond is hard enough to be able to scratch Tungsten Carbide.

Tungsten carbide is a material that is very difficult to cut, mainly owing to its extreme wear resistance. Its high value of yield strength, accompanied by extreme brittleness, renders its machinability extremely poor, with most tools failing. Even when cutting with tool materials of the highest quality, its mode of cutting is mainly brittle and marred by material cracking.
