This end mill blends robust geometry with a coating designed to endure demanding roughing conditions. The 4‑flute configuration provides efficient chip evacuation while maintaining steady cutting action, making it well suited for aggressive pre‑machining in a variety of metals. The combination of powder metallurgy HSS‑E and Alcrona Primax coating enhances wear resistance and heat tolerance, helping to extend tool life in tough materials. A 20 mm Weldon shank ensures strong retention in standard tool holders, while the extended neck relief supports deeper cuts and cleaner shoulders without sacrificing rigidity. Ideal for production environments where reliability and consistent performance matter across multiple steel and alloy families.
