GNDIS Type for Internal Grooving

For small bores with minimum bore diameters from Ø14mm

Reduces vibration during grooving by employing the same high-rigidity

holder design of the GND series

Increased tool life through one-piece body structure

Uses special 2-cornered inserts (GXM type)

Wide pocket improves

chip evacuation

Die steel

Notice: Different insert sizes

GNDIS type: use smaller GXM type inserts One piece body structure

GNDI type: use standard GCM inserts

Coolant is directed onto

rake face of cutting edge

Improved Chip Management Chattering Resistance Performance
