Cutting Performance Characteristics
Eliminates Vibration Wide range of application processes
Applicable for grooving, turning, copying, facing,
Reduces vibration up to 30% compared to conventional grades boring and cut-off.
thanks to its high-rigidity design. Achieving stable tool life
An array of chipbreakers improves the efficiency
Special die steel in chip control in various applications and prevents
unexpected damages caused by chip blockade.
Achieving smooth cutting and high efficiency machining
Holders utilizing one-piece body construction made of
special steel, reduce vibration by 30% during machining
as compared to conventional types.
