Designed to handle mid to heavy metal removal with consistent accuracy, this end mill excels in deep pockets and precise shoulder features. The powder-metallurgical HSS-E construction provides enhanced hardness and wear resistance, extending tool life in challenging materials. The 64.5 mm reach from neck relief allows deeper milling without retooling, while the Weldon shank ensures a secure, repeatable grip in collets and holders. With its 30° helix and 12° rake angle, it delivers efficient chip clearance and clean shoulders, making it a reliable choice for free-machining steels and copper-family materials across automotive, general engineering, and fabrication environments.
