Milling Toolholder for Heavy-Duty Cutting - SCHUNK


The new SINO-R from SCHUNK is a maintenance free toolholder especially well suited for rough milling. The universal toolholder is based on an expansion technology system with a solid body as a pressure medium quickly clamping the cutting tool by using a simple actuation wrench. This simple operation saves unproductive machine down-time.

The excellent interaction of high radial rigidity and great dampening characteristics are special features that increase the smooth running of the tool. The result is a high tool life and increased material removal rates.

An additional plus for the user: the toolholder is flexible thanks to the use of intermediate sleeves. Nearly all common tool shank diameters can be clamped.
SINO-R holds your tool securely, with a maximum torque transmission (850 Nm (627 Ft-lb)), at a clamping diameter of 32 mm (1.25”). It is precision-balanced standard to G 6.3 at 15000 rpm.
