With its cobalt-based HSS-E composition, this end mill delivers improved wear resistance and red hardness, enabling longer tool life under demanding roughing conditions. The 4-flute configuration optimizes metal removal rates while maintaining control and surface integrity. The Weldon shank provides secure clamping to minimize runout, supporting precise pockets and slots. Its 13 mm length of cut offers deeper reach for profiling and finishing in a single setup, while the 57 mm overall length gives versatility across small to mid-depth milling tasks. This end mill is a reliable, high-performance choice for shops seeking consistent, efficient roughing in steel and copper alloys.
