  • GNDIS Type for Internal Grooving
  • For min. bore diameters from ø14mm or bigger accepted.
  • Double-cornered, molded insert similar to the GND series with excellent chip control that prevents chip jamming.
  • Mono-block structure, Die Steel body that reduces chattering while extending the holder's tool life.

The wide pocket improves chip evacuation

Note: Use GXM type inserts exclusive for GNDIS type. GCM type and GCG type are not compatible because their total lengths are different.
