Характеристики и преимущества

ATTENTION: Inserts with corner radius .158" (4.0mm) require insert pocket modifications.

Designed for aerospace airframe structural component machining, targeting maximum metal removal rates (MRR).

Adjustable coolant nozzles support chip evacuation and control heat in the cutting zone.

Large helix ensures hassle-free chip evacuation event at highest metal removal rates (MRR).
