The combination of a 13 mm cutting diameter and a 26 mm length of cut supports efficient material removal in demanding workpieces, while the 83 mm overall length and 37.5 mm reach with neck relief provide depth flexibility without sacrificing rigidity. The powder‑metallurgical HSS‑E substrate paired with the Alcrona Primax coating offers enhanced wear resistance and longer tool life under high‑load roughing conditions. The NRA asymmetrical coarse pitch geometry improves chip evacuation and reduces built‑up edge, helping maintain stable cutting forces and smooth transitions in challenging materials. This end mill is an reliable choice for production environments that require consistent performance across a variety of metals and alloys.
