The 4-flute NRA geometry enables efficient material removal with stable cutting forces, helping maintain steadier feeds and finishes during roughing. The powder-metallurgical HSS-E substrate, combined with the Alcrona Primax coating, enhances wear resistance and provides improved chip control under heavy loads, helping extend tool life in mixed-material environments. The extended reach with neck relief supports plunging and pocket-accessible milling while preserving workpiece surface integrity. Paired with a secure 12 mm Weldon shank, this end mill delivers repeatable clamping and consistent performance in standard tool holders, making it a dependable choice for high-volume production or complex machining scenarios.
