Aluminum milling cutters with DLC surface coating are made of 0.6 grain tungsten steel.

The thickness of DLC coating is only 0.01-0.2μm, which does not affect the sharpness of the cutting edge, and high red hardness, high temperature resistance, because of the low coefficient of friction of this coating, wear-resistant, 2 times longer than the life of uncoated cutting edges, and it is easier to discharge the aluminum chips, so the tool is not easy to break.

Satisfies various situations of machining.
