Schunk 1407722 Hydraulic Tool Chuck CAT40 0.5 Inch Bore

Product Description

The SCHUNK 1407722 is a hydraulic tool chuck with a CAT40 taper shank connection designed for use in CNC machining centers and milling applications. It accepts a 0.5-inch (12.70 mm) bore and provides hydraulic clamping force to hold cutting tools with high concentricity. The chuck features through-coolant capability, directing coolant directly to the cutting edge for improved chip evacuation and tool life. Total indicator runout (TIR) is rated at 0.003 mm, making it suitable for precision finish milling, reaming, and drilling operations. Installed by CNC machinists and toolroom technicians, this chuck is a direct-mount, no-adapter solution for CAT40 spindle interfaces.

This hydraulic chuck is intended for use in vertical and horizontal machining centers equipped with a CAT40 spindle. The 0.5-inch bore accommodates standard shank cutting tools including end mills, drills, and reamers. A clamping depth of 46.99 mm provides solid tool engagement, and the 23.88 mm nose diameter and 23.88 mm projection suit close-tolerance work envelopes where spindle-to-workpiece clearance is limited. Through-coolant support makes it well-suited for deep-hole drilling and high-speed milling where flood coolant alone is insufficient.

Key Features

• CAT40 taper shank for direct mounting to CAT40 spindle interfaces without adapters
• Hydraulic clamping mechanism delivers consistent, high-force tool retention
• 0.003 mm TIR for precision concentricity in finish and semi-finish operations
• Through-coolant capable for directed coolant delivery to the cutting zone
• 46.99 mm clamping depth ensures secure tool grip on standard shank lengths
• Compact 23.88 mm nose diameter supports tight-clearance machining setups

Compatibility

Designed for use with CAT40 spindle machines accepting standard CAT40 taper shank toolholders and compatible with 0.5-inch shank cutting tools.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machining center spindle before mounting or removing the chuck. Use a CAT40-compatible toolholder tightening fixture and drawbar torque specifications provided by the machine manufacturer. Verify TIR with a dial test indicator after installation before returning the spindle to production use.
