The QS toolholding system by Sandvik Coromant is an innovation for Citizen machines. Each system kit includes a stop, two spring-loaded wedges and a short toolholder, with shank sizes ranging from 8×8 mm to 16×16 mm in diameter.

Because of its design, the system can reduce downtime and improve productivity, the company says. With this quick-change solution, insert indexing times are reduced by 2 minutes, and diameters can be machined multiple times without having to change the machine's settings.

Because the system is designed for easy operation and use, a single screw controls clamping and unclamping capabilities. The system also features a spring-loaded wedge, which secures the short holder in place and eliminates cumbersome handling. The QS system's insert edge position is automatically set up be contact between the short holder and the stop and does not require adjustments.
