Accupro 1527334 Hydraulic Chuck CAT40 3/4 Inch

Product Description

The ACCUPRO 1527334 is a CAT40 hydraulic tool holder chuck designed for precision milling and machining applications. It accepts a 3/4 inch bore and delivers a total indicator reading (TIR) of 0.000010 inch, making it well-suited for high-speed, tight-tolerance work. The chuck supports through-coolant delivery and is balanced to 25000 RPM. At 4.25 inches overall length and 2.36 inches body diameter, it fits standard CAT40 spindle interfaces. Licensed machinists and toolroom technicians are the primary installers of this style of holder in CNC machining center environments.

This hydraulic chuck is used in CNC vertical and horizontal machining centers equipped with CAT40 spindles. It is appropriate for high-speed finishing operations where runout control is critical, such as reaming, boring, and precision end milling. The through-coolant feature supports chip evacuation and tool cooling at elevated spindle speeds. This part replaces SKU 56509607.

Key Features

• CAT40 taper shank for direct spindle mounting on CAT40-equipped machining centers
• 3/4 inch bore diameter for standard shank tooling
• TIR of 0.000010 inch for high-precision, low-runout performance
• Balanced to 25000 RPM for high-speed spindle compatibility
• Through-coolant capable for improved chip control and tool life
• 51.00 mm clamping depth provides secure grip on tool shanks

Compatibility

Designed as an OEM-style replacement for CAT40 spindle machining centers. Replaces SKU 56509607.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with CAT40 tooling systems. Power down and lock out the spindle drive before mounting or removing the tool holder. Use a calibrated torque wrench and follow the machine tool manufacturer guidelines for drawbar retention force. Verify runout with a test indicator after seating to confirm TIR is within specification before cutting.
