Schunk’s Tendo-ES is a short hydraulic expansion toolholder that allows the tool to be clamped directly in the mounting taper, thus supporting the shank via the spindle. The result is higher holding forces for transferable high torques, as well as additional space in the machining area.
The toolholder is suitable for use in rough machining, HPC/HSC, and for drilling, reaming, tapping, thread milling, and thread forming. The company reports brilliant surfaces, dimensional accuracy, and long tool life as benefits of the toolholder.
Available for the SK 40 and CAT 40 interfaces, standard Tendo sleeves can be used to clamp smaller tool shank diameters and intermediate sleeves offer flexibility.
