Solid Carbide Endmills G550 - Ball Nose Type - 4F 鎢鋼球型銑刀 - 標準型 - 4 刃 . UNICO Coating provides superior wear resistance and reduces the coefficient of friction. Solid Carbide Endmills . Suitable for HRC 30 to HRC 55 Ordinary Steel, Alloy Steel, Cast Iron, Heat-Resistant Steel, Copper, FRP, etc. . It provides an excellent surface due to better surface grindings. . New tool geometry increases wear resistance and cutting force is decreased. . Multiple flutes design improves the cutting surface. Radius Dia.
