With a 35° helix and a 12° rake, this end mill delivers steady cutting action and effective chip evacuation across a variety of materials, helping to minimize built-up edge and improve surface finish in roughing passes. The combination of 6 flutes and the NRA profile provides robust material removal rates while maintaining control and stability in demanding milling scenarios. The DIN 844 K Weldon shank ensures a secure, repeatable fit in standard holders, making it a reliable choice for high-volume machining of steel components, castings, and alloy workpieces.
