Designed to remove material efficiently while maintaining control and edge integrity, this end mill benefits from a hardened HSS-E substrate and a durable Alcrona Primax coating that reduces wear and supports multiple roughing passes. The 35° helix and 12° rake contribute to steady cutting forces, improved chip evacuation, and a smoother finish, making it a dependable choice for heavy-duty milling at the machine shop or production floor. With DIN 844 K compatibility and a Weldon 25 mm shank, it locks securely in the holder for consistent performance through long runs and challenging workpieces.
