  • TiSlN Coating for Wear Resistance: Extends tool life and withstands higher cutting temperatures, preserving sharpness through demanding operations.
  • Square Edge for Precise Cuts: Delivers clean starts, accurate corners, and reliable finishes in pockets, slots, and surface milling.

This end mill is designed to help you achieve consistent, high-quality results with exotic materials. Its combination of precise geometry and durable coating supports reliable performance, reduces downtime, and helps your work maintain tight tolerances across a variety of challenging milling tasks.
