Tool 120m040FA

Heavy roughing cuts in hardened steel generate heat that breaks down uncoated tools within minutes.

Ball nose geometry at 4" cutting diameter follows contoured surfaces without leaving flat-bottomed transitions.
The 4-inch cutting diameter handles large-scale profiling and contouring operations where smaller cutters would require excessive stepover passes.
TiAlSiN coating maintains cutting edge integrity at elevated temperatures by forming a protective aluminum oxide layer during machining.
This thermal barrier reduces crater wear and extends tool life in interrupted cuts through hardened workpieces.
Three flutes provide balanced chip evacuation while maintaining sufficient core strength for the extended reach.
The rounded tip produces smooth transitions on contoured surfaces without the step marks left by flat-bottomed cutters.
