This end mill is engineered for high-efficiency roughing with a 6-flute configuration that promotes steady chip evacuation and reduced vibration. The powder-metallurgical HSS‑E substrate, paired with the Alcrona Primax coating, delivers improved wear resistance and longer tool life under heavy feeds and speeds. Its 35° helix and 12° rake optimize cutting action for shoulder and slot milling, helping you achieve aggressive material removal without sacrificing accuracy or surface integrity. With a DIN 844 L Weldon shank and a generous reach, you can tackle deep cavities and thick-walled components in a single setup.
