Characteristics

Wide range of application processes

Applicable for grooving, turning, copying, facing, boring and cut-off.

Achieving stable tool life

An array of chipbreakers improves the efficiency

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.

Achieving high precision grooving widths with moulded inserts

Grooving insert width tolerance of ±0,03mm over the

entire range

Cutting Performance

Eliminates Vibration Ensures both high rigidity and good chip evacuation

Reduces vibration up to 30% compared to conventional grades Internal

thanks to its high-rigidity design. Wide pocket improves chip evacuation Special die steel
