High feed milling cutters with six cutting edge inserts

Featuring robust cutter design for high productivity

Applications & Features

High feedFace millingSlottingPocketingRampingPlungingHole enlarging

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.
