The GFJ68 series NC Mill Hardened Steel carbide milling cutters feature a 2 flute design ideal for slotting and a ball nose design ideal for radiused applications and profiling. NC Mill Hardened Steel cuts through alloy steel, tool steel & hardened steel <60HRC at speed. The high quality nanograin carbide substrate, combined with a unique Z-coating, equips the NC Mill Hardened Steel to effectively tackle high hardness & high temperature machining at speed. They are supplied with a plain shank, most suitable for being clamped in an ER collet chuck.
