    Maximized machine utilization

    QS™ holding system is a quick change system developed specifically for sliding head machines. The system of tool holders, stops and wedges offer stable tool clamping and secure insert edge position for good repeatability and accuracy.

    Process security with high precision

    The QS™ tool holders are available with precision coolant, which improves chip control, tool life and component quality. The coolant is easily connected thanks to dedicated coolant connection kits.

    Easy handling for reduced downtime

    The single screw release function simultaneously pulls out the wedge and holder, for quick tool change and set-up. No diameter adjustment is necessary thanks to the back stop, which ensures close repeatability tolerance for the insert edge position.
