With four flutes and a thoughtful geometric design, this end mill enables efficient chip clearance and steadier engagement in tough materials. The powder-metallurgy HSS-E core combines wear resistance with toughness, helping extend tool life in aggressive roughing passes. The NRA asymmetrical core pitch optimizes cutting efficiency and minimizes vibration, while the 35° helix and 12° rake angle promote smooth chip evacuation and consistent shoulder milling results. The 83 mm overall length and 37.5 mm reach provide flexibility for deeper pockets and diverse setups, and the 12 mm Weldon shank ensures secure, repeatable seating in compatible holders. This end mill is well-suited for shop floors that tackle mixed-material roughing tasks, delivering reliable performance from steel to high-temperature alloys.
