High feed milling cutters with six cutting edge inserts
Featuring robust cutter design for high productivity
Applications & Features
Applications
Features
1. Economical double-sided inserts with six cutting edges
– 1.5 to 3 times greater number of cutting edges per insert compared with conventional high feed milling inserts.
– Reduced cost per insert when machining stainless steels and difficult materials, where inserts demonstrate rapid wear.
2. Designed for tool reliability and stability
– Robust cutting edge design forms an obtuse angle, eliminating insert fracture during machining.
– A large contact face on the insert seat provides secure insert retention.
3. Excellent ramping capability
– Longer inner cutting edge allows higher ramp-down capabilities to promote higher productivity.
– Increased max ramping angles allow productivity boosts in linear and helical ramping operations.
