GLS (GripLock Swiss) is Kemmer’s modular system designed specifically for sliding-head machines, ensuring precise repositioning and a stable interface. The GLS range includes cartridges for threading, parting-off, ISO inserts and grooving, all available with internal coolant and compatible with 12×12 and 16×16 square shanks.

The system provides maximum versatility: a single shank allows the use of cartridges on both sides.
