Solid Carbide Endmills G550 - Long Shank Ball Nose Type - 2F 鎢鋼球型銑刀 - 長柄型 - 2 刃 . UNICO Coating provides superior wear resistance and reduces the coefficient of friction. . Suitable for HRC 30 to HRC 55 Ordinary Steel, Alloy Steel, Cast Iron, Heat-Resistant Steel, etc. . It provides an excellent surface due to better surface grindings. . New tool geometry increases wear resistance and cutting force is decreased. . Suitable for high speed profile surface milling. EPBEC2 Radius Dia.
