Large diameter ball nose work puts significant thermal stress on the cutting edge during extended profiling passes.

Ball nose geometry at 3" 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.
At 3" cutting diameter, the TiAlSiN coating becomes critical for heat management and wear resistance during heavy material removal.
The aluminum content in the coating maintains hardness at elevated temperatures while the silicon component reduces friction.
This combination extends tool life when machining large aerospace components or heavy industrial molds where conventional uncoated tools would fail from thermal breakdown.
