Ideal for 3D contouring, pocketing and finishing of complex surfaces in molds, dies and precision components.
2 flute ball nose design provides large chip space and smooth chip evacuation, especially suitable for semi-finishing and finishing in hardened steels.
Short flute length increases rigidity, reduces deflection and improves dimensional accuracy in deep cavity machining.
High-performance coating delivers excellent wear and heat resistance, enabling stable cutting in materials up to HRC45–55.
Recommended for high-speed CNC machining centers used in mold and die, automotive, aerospace and general engineering industries.
