Complex 3D surfaces in hardened steels create heat buildup that dulls uncoated cutters quickly.

  • Ball nose geometry at 0.25" cutting diameter follows contoured surfaces without leaving flat-bottomed transitions.
  • The rounded tip produces smooth transitions on contoured surfaces and mold profiles without leaving flat-bottomed steps.
  • Three flutes balance chip clearance with cutting engagement on curved geometry where maintaining constant surface contact matters.
  • The TiAlSiN coating handles the thermal cycling that comes with interrupted cuts on hardened materials.
  • The aluminum content in the coating forms a protective oxide layer at higher temperatures, extending tool life when working abrasive alloys.
  • The 0.25" cutting diameter provides access to detailed features while maintaining rigidity for consistent surface finishes.
