The combination of powder-metallurgical HSS-E with the Alcrona Primax coating provides improved wear resistance and heat performance, helping extend tool life in tough materials. The 4-flute geometry offers efficient chip evacuation and steady cutting in heavy roughing passes, while the 35° helix and 12° rake angle contribute to smoother cutting action and better surface finishes. With a standard Weldon shank and DIN 844 K designation, this end mill integrates smoothly into existing tooling setups and high-capacity milling operations.
