The Tendo family of hydraulic expansion toolholders from Schunk now comes in a super-slim version. The Tendo LSS has been optimized to keep interfering contours to a minimum. It can be used to access difficult parts of a workpiece and function in working areas where appliances create difficult conditions.

The toolholder is available for SK 40 mounting shanks and features a balancing quality of G 2.5 at 25,000 rpm for HSK-A63.
