Tool 120i125LFA

Tight radius work in hardened steels creates heat buildup that degrades surface finish and shortens tool life.

Ball nose geometry at 0.125" 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 properties that become critical when working hardened materials at the small 0.125" cutting diameter.
The coating's aluminum content forms a protective oxide layer at elevated temperatures, extending tool life in interrupted cuts and high-temperature alloys.
Heat dissipation becomes more challenging as diameter decreases, making the coating particularly beneficial for detailed work in tough materials.
