HRC 55 Deg Tungsten Steel 2 Flutes Ball Nose End Mills

Raw Material:
Use Zigong ZK30UF, high hardness and good wear resistance.
Coating:
TiSiN, containing silica, very high surface hardness and high thermal resistance.
Double-edge design improves rigidity and surface finish effectively. Cutting edge over the center reduces the cutting resistance. High capacity of junk slot benefits chip removal and increases machining efficiency. 2 flutes design is good for chip removal, easy for vertical feed processing, widely used in slot, and hole processing.
