Grooving Tools Small Vibration Large Vibration SEC-Grooving Tools GND Type ■ Features ● Wide application range Applicable for grooving, traverse cutting, profiling, necking, facing and internal boring. ● Stable tool life A variety of chipbreakers improve chip control in various applications. Prevents sudden breakages due to chip clogging. ● Achieving high efficiency machining with reduced chattering The mono-block structure and die steel body reduce vibration F during machining around 30% compared to conventional tools● Higher edge width precision even with unground inserts High-precision sintering technology achieves cutting edge width precision of ±0.03mm for widths from 1.25 to 6.0mm ■ Cutting Performance (front cutting edge angle of 0° or 5°) Reduce Chattering Both high rigidity and good chip evacuation performance Internal High rigidity design reduces chattering by up to 30% as compared to conventional tools.
