Tool 120m040LFA
Large diameter ball nose cutters face heat buildup and premature wear when machining hardened steels and superalloys.
- The 120m040LFA is a 4-inch diameter solid carbide ball nose end mill designed for steel, iron, titanium, and nickel alloys.
- The TiAlSiN coating provides aluminum oxide formation at elevated temperatures, creating a thermal barrier that extends tool life in demanding ferrous applications.
- Three flutes maintain chip evacuation while providing adequate cutting engagement across the curved profile geometry.
- The rounded tip generates smooth surface transitions on complex 3D profiles and large cavity work.
- This geometry eliminates flat-bottom stepping that occurs with conventional end mills on contoured surfaces.
- The coating chemistry performs particularly well in interrupted cuts common to aerospace and mold making applications.
