120 Series

Tool 120m050A

Heavy stock removal on hardened steels generates heat that breaks down cutting edges faster than the part can be completed.

Ball nose geometry at 5" 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.
The TiAlSiN coating provides a barrier against heat buildup during extended cuts in harder materials.
This coating maintains its lubricity at elevated temperatures where uncoated carbide would begin to wear rapidly.
The 5" cutting diameter handles substantial material removal while the ball nose geometry prevents step marks on 3D contours.
