120 Series

Tool 120m040LA

Heavy profiling cuts on hardened steel generate heat that degrades tool life and surface finish.

Ball nose geometry at 4" cutting diameter follows contoured surfaces without leaving flat-bottomed transitions.
The rounded tip produces smooth transitions on contoured surfaces and mold profiles.
Three flutes balance chip clearance with cutting engagement on curved geometry.
TiAlSiN coating provides thermal barrier protection during aggressive profiling operations.
The aluminum content in the coating maintains hardness at elevated temperatures while the silicon component reduces crater wear on the rake face.
This 4-inch diameter cutter handles large-scale die work and aerospace components where surface quality matters.
