Grooving Tool
Rigid Body The GND series features a monoblock structure and die steel bodies, which not only provides for stable processing but controls vibration. Not solely for grooving, the GND series features holders for groove-turn, proling, and face grooving.
Wide Variety of Chipbreakers
Full lineup of ten different chipbreakers for the GND covers a wide slate of machining operations, conditions and workpiece materials!
