This end mill pairs a robust 4-flute geometry with a long cutting length, enabling efficient material removal in challenging pockets and slots. The Alcrona Primax coating reduces wear and helps extend tool life in tough alloys, while the powder-metallurgical HSS-E core provides a balance of hardness and toughness for reliable performance. The NRA asymmetrical coarse pitch supports effective chip evacuation and stability in deeper cuts, and the 35° helix along with a 12° rake angle improve cutting efficiency and surface finish on a variety of workpieces.
