Accupro 1527333 Hydraulic Chuck CAT40 5/8 Inch Bore

Product Description

The ACCUPRO 1527333 is a hydraulic tool holder chuck designed for CNC machining centers using a CAT40 taper shank interface. It accepts cutting tools with a 5/8 inch bore diameter and delivers high-precision clamping through internal hydraulic expansion. The chuck is balanced to 25,000 RPM and holds a total indicator runout (TIR) of 0.000010 inch, making it suitable for high-speed finishing, reaming, and precision boring operations. Licensed machinists and CNC setup technicians install this holder as part of a tooling system requiring consistent concentricity and vibration-free performance at elevated spindle speeds.

This chuck is suited for use on vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. The 4.25 inch overall length and 34.50 mm nose diameter fit standard CAT40 tooling configurations in both production and job-shop environments. Through-coolant capability allows directed coolant delivery to the cutting zone, extending tool life and improving chip evacuation in deep-pocket or high-feed applications. This holder is a fit for shops running tight-tolerance work where runout and balance directly affect surface finish and tool life.

Key Features

• CAT40 taper shank for direct mounting in CAT40-spindle machining centers
• 5/8 inch bore diameter with hydraulic clamping for secure, concentric tool grip
• Balanced to 25,000 RPM for high-speed spindle compatibility
• TIR of 0.000010 inch for precision-critical operations
• Through-coolant capable for directed coolant delivery at the cutting edge
• 49.00 mm clamping depth provides secure tool engagement

Compatibility

Designed as an OEM-style hydraulic chuck for CNC machining centers with a CAT40 spindle interface accepting 5/8 inch shank cutting tools.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the machining center spindle before inserting or removing any tool holder. Use the correct CAT40 retention knob torque procedure per the machine tool manufacturer specifications and always verify TIR with a dial indicator after seating. Do not exceed the rated balance speed of 25,000 RPM.
