SCHUNK - Hydraulic expansion toolholder

The SCHUNK TENDO Silver is a high-precision hydraulic expansion toolholder designed for reliable clamping and excellent machining results in milling, drilling and reaming operations. Its hydraulic expansion technology ensures uniform clamping pressure around the tool shank, delivering outstanding run-out accuracy, vibration damping and surface finish — making it an ideal choice for high-speed and precision machining applications.

Key Highlights:

• Hydraulic expansion clamping technology provides uniform 360° tool gripping for exceptional concentricity.
• High run-out accuracy (typically ≤ 0.003 mm) ensures superior surface finish and dimensional precision.
• Excellent vibration damping improves tool life and enables higher cutting parameters.
• Quick and easy tool changes using a simple hex key — no special equipment required.
• Wide application range including milling, drilling, reaming and finishing operations across steels,
