This tool is designed for robust performance across a range of machining scenarios. The HSS-E powder metallurgical core paired with the Alcrona Primax coating helps maintain edge integrity and reduce wear over extended use, while the 3-flute geometry supports efficient chip evacuation for clean slots. The short series and neck relief enhance rigidity in tight pockets, making it well-suited for precise slots, pockets, and shoulder features in demanding materials. The DIN 327 D Weldon shank ensures secure, repeatable performance with standard toolholders.
