Graphite Long-necked flat end mill  are diamond coated. The high-performance diamond coating film provides excellent wear resistance for long machining times.

Selection of high quality cobalt 6 tungsten carbide rods, which can strengthen the bond with diamond coating, have high adhesion and the coating is not easy to come off.

Suitable for processing graphite parts, heat bending 3D molds, carbon brazing, tungsten copper fine milling and semi-fine milling.

Air cooling is recommended.
