This end mill is optimized for high-torque roughing in a variety of materials. The 4-flute geometry provides a balance between aggressive material removal and efficient chip evacuation, helping maintain steady cutting forces and extended tool life. The Alcrona Primax coating, combined with a powder-metallurgy HSS-E substrate, enhances wear resistance and toughness, delivering predictable performance across tough metals. The flatted 10 mm Weldon shank improves grip in standard holders, reducing slip and ensuring stable milling during demanding operations. Suitable for shoulder milling, slot milling, and ramping, this tool offers reliable results in production environments that require consistent roughing performance across multiple workpiece materials.
