120 Series

Tool 120m050LFA

Heavy cuts in tough alloys generate heat that shortens tool life and degrades surface finish.

Ball nose geometry at 5" cutting diameter follows contoured surfaces without leaving flat-bottomed transitions.
The TiAlSiN coating on this 5" diameter cutter provides thermal barrier protection during extended roughing and semi-finishing operations.
Aluminum content in the coating maintains hardness at elevated temperatures while the silicon component reduces friction against chip flow.
Three flutes balance chip evacuation with cutting engagement on curved surfaces and complex 3D profiles.
The rounded tip produces smooth transitions on contoured geometry without leaving flat-bottomed steps.
Ball nose geometry allows the cutter to follow complex surface paths in mold work and aerospace components.
