Designed for high-speed roughing, this end mill combines a tough HSS-E core with a wear-resistant Alcrona Primax coating to extend tool life in challenging materials. The 35° helix and 12° rake angle balance aggressive material removal with controlled cutting forces, helping to reduce chatter and improve surface integrity during deep pocketing and entrance ramps. The long reach and neck relief provide ample clearance for deep slots and complex pockets, while the Weldon 16 mm shank ensures a secure, vibration-damping fit in standard tool holders. Whether you're roughing carbon steel, stainless steel, or high-temperature alloys, this end mill is built to deliver consistent performance and dependable results.
