This end mill is built to handle demanding roughing tasks with stability and precision. The asymmetrical fine-pitch HRA geometry helps balance cutting forces, reducing vibration, while the powder-metallurgical HSS-E base paired with the Alcrona Primax coating minimizes wear and heat generation. The 12 mm Weldon shank provides a rigid, repeatable grip, ensuring accuracy during deep pockets and complex ramping operations. With a 26 mm length of cut and 37.5 mm neck relief, you gain reach and clearance for intricate milling paths, all while adhering to the common DIN 844 K standard for broad compatibility in machine setups.
