Schunk 1447936 Hydraulic Tool Chuck CAT50 5/8 Bore

Product Description

The SCHUNK 1447936 is a hydraulic tool chuck with a CAT50 taper shank interface, designed for high-precision milling and boring operations on CNC machining centers. It accepts tooling with a 5/8 inch (15.88 mm) bore and delivers a total indicator runout (TIR) of 0.003 mm, making it suitable for finish machining where concentricity is critical. The chuck is balanced to 25,000 RPM and features through-coolant capability to support high-speed cutting with direct coolant delivery to the tool tip. Installation and servicing are performed by machining technicians working on CNC turning and milling equipment.

This hydraulic chuck is intended for use on CAT50 spindle machines in industrial and production machining environments. The 81 mm projection and 1-13/16 inch nose diameter suit setups where moderate reach and rigid tool clamping are required. Through-coolant support makes it well-suited for deep-cavity work, high-speed finishing passes, and applications where chip evacuation and heat management at the cutting zone are priorities. It is appropriate for both production shops and toolroom applications running CAT50-equipped machining centers.

Key Features

• CAT50 taper shank interface for direct spindle mounting on compatible machining centers
• 5/8 inch (15.88 mm) bore diameter accommodates standard shank tooling
• 0.003 mm TIR for high-concentricity tool holding in finish and semi-finish operations
• Balanced to 25,000 RPM for high-speed machining applications
• Through-coolant design delivers coolant directly to the cutting edge
• 38.60 mm clamping depth provides secure hydraulic grip on tool shanks

Compatibility

Designed as an OEM-style hydraulic tool chuck for CAT50 spindle machining centers accepting standard 5/8 inch bore tooling with through-coolant capability.

Installation Notes

Installation should be performed by a qualified machining technician following the machine tool manufacturer's spindle tooling procedures. Power down and lock out the machining center spindle before mounting or removing the chuck. Use the appropriate CAT50 retention knob and drawbar torque specification as defined by the machine builder. Do not exceed the rated RPM balance specification, and verify tool runout with a dial indicator after clamping.
