This end mill is built to handle demanding roughing tasks with stability and precision. The NRA geometry reduces cutting forces for smoother engagement in shoulders and pockets, while the 4-flute design preserves rigidity and promotes effective chip evacuation. The powder-metallurgical HSS-E substrate paired with the Alcrona coating enhances wear resistance and tool life in tough materials, helping you push higher feed rates without sacrificing surface finish. The Weldon shank delivers secure, repeatable clamping in standard holders, making it a reliable choice for production environments that require consistent performance across long milling passes.
