Tool 120i375A

3D profiling and contouring demand a cutter that follows the surface without leaving a flat-bottomed step.

Ball nose geometry at 0.375" 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.
This 0.375" diameter cutter carries a TiAlSiN coating.
The aluminum-silicon nitride composition maintains hardness at elevated temperatures while reducing friction during cutting.
Heat buildup becomes problematic in these materials, particularly titanium and nickel alloys, where work hardening can destroy uncoated edges rapidly.
The coating extends tool life in interrupted cuts common to 3D profiling work.
Surface finishes remain consistent longer between tool changes.
