Hydraulic clamping technology delivers uniform radial force around the tool shank, producing a total indicator runout (TIR) of 0.003 mm for accurate, repeatable cutting performance. Rated to 25,000 RPM, this chuck supports high-speed machining operations in ferrous and non-ferrous materials. It is installed and serviced by qualified machine tool technicians and CNC maintenance personnel.\u003c\/p\u003e\u003cp\u003eThis chuck is suited for vertical and horizontal CNC machining centers equipped with a CAT40 spindle interface. The 3\/4-inch hole diameter accommodates a common shank size, while the 64 mm projection and 51 mm clamping depth (2.0 inches) provide adequate reach and grip for a wide range of tooling setups. Through-coolant capability channels cutting fluid directly to the tool tip, supporting extended tool life and chip evacuation during deep-pocket and high-feed operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank connection for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eHydraulic clamping mechanism achieves 0.003 mm TIR for high-precision tool holding\u003c\/li\u003e\n\u003cli\u003e25,000 RPM maximum speed rating supports high-speed machining applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant passage delivers fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hole diameter accommodates common straight-shank tooling\u003c\/li\u003e\n\u003cli\u003e51 mm (2.0 inches) clamping depth provides secure tool engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hydraulic tool chuck for CNC machining centers with a CAT40 spindle interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by a qualified CNC machine tool technician with the spindle powered down and locked out per applicable machine safety procedures. Use the appropriate CAT40 retention knob and drawbar torque specification as defined by the machine tool manufacturer. Do not exceed the rated 25,000 RPM balanced speed.
