[Features] ● Uses an innovative additive manufacturing method using a 3D printer (metal powder). ●Can be used as an alternative to shrink fit chucks for all precision machining and slim shapes. ● Compared to conventional hydro chucks, the hydraulic clamping point is designed to be as high as possible, increasing coaxiality and gripping force. ●Excellent run-out accuracy and vibration damping function extend tool life and improve machining accuracy. ●Although the tip is 3°tapered, it achieves a tapered shape comparable to shrink fitting. (3 tip mouth diameter 10mm) ●Compatible with tool shanks with flat parts, and empty tightening will not cause failure. ●Torque wrench is unnecessary due to the stopper function.
