Grooving & Parting-Off Low Vibration Strong Vibration Grooving Tool Holders GND Type 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 Special steel Single-piece construction  Oil hole Improved chip evacuation  Oil hole Coolant is directed onto rake Single-piece construction face of cutting edge Stable, Reduced Vibration Unstable Vibration Large Vibration GND Type Conventional Tool GND Type Comp.
