Tool 120m080A

Large diameter ball nose work puts thermal stress on both the cutter and workpiece. Heat buildup becomes the limiting factor on heavy profiling cuts.

Ball nose geometry at 8" 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 extends tool life in high-temperature applications by maintaining hardness at elevated cutting temperatures.
The coating's aluminum content forms a protective oxide layer that reduces heat transfer to the substrate carbide.
At 8-inch cutting diameter, this end mill handles large format toolpath requirements where smaller cutters would require excessive stepover passes.
