It is Made with wear & heat resistant tungsten carbide. While the high speed drill touching the work piece and giving it downward force, the heat created by friction will melt the surface and the burrs will be made by the force on the surface. It require the drill has outstanding rigidity and hardness in the operation.
Tungsten carbide mold.
For dividing silicon steel to sheets. Suitable hardness sharp edge, which makes the divided sheets smooth and free of burrs. Life time is over 50 times longer than that of skd11.
For forming powder by powder metallurgy/electronics manufacturers. The die is made with non-magnetic tungsten carbide. Life time is over 50 times longer than that of non-magnetic steel .
