Toolholders
Hydraulic Expansion Toolholder
The Schunk Tendo-ES is a short, hydraulic-expansion toolholder that allows the tool to be clamped directly in the mounting taper. The tool shank is supported via the spindle, and the result is a high holding force for transferable high torque and additional space in the machining area.
