SINO-R Expansion Toolholders

The specialist for thread milling

With SINO-R, SCHUNK is offering a universal toolholder for all-around use on the basis of expansion technology. In terms of quality and versatility, the SINO-R expansion toolholders are especially strong when compared to conventionally used toolholders such as WELDON, Whistle Notch, or power-actuated toolholders. SINO-R is ideally suitable for large volume cutting, as well as thread milling, drilling and cutting.

Our performance promise. Your benefits.

  • Optimum ratio between clamping force, rigidity, and damping
  • Easy tool change
  • Versatile clamping range due to intermediate sleeves
  • All commercially available tool shank types can be clamped
  • When clamped, the tool transfers torques of up to 800 Nm (tool shank Ø 32 mm/shank quality h6)
  • SINO-R

    SINO-R

    With SINO-R, SCHUNK is offering an expansion toolholder on the basis of expansion technology. Three characteristics make the SINO-R range unbeatable in terms of quality and productivity when it comes to thread milling. The high radial stiffness prevents deflection of the tool. The higher torque transmission allows the tool to be used to its full potential. And the top vibration damping produces the best thread surfaces with no chatter marks.
