Sandvik Coromant 6426569 Hydraulic Chuck Sleeve

Product Description

The SANDVIK COROMANT 6426569 is a hydraulic chuck sleeve designed for precision toolholding applications in CNC machining environments. With a 0.5 inch inside diameter and a 1.1811 inch head diameter, this sealed sleeve integrates with hydraulic chucks to provide accurate, vibration-dampened grip on cutting tools. The length under head measures 2.2047 inches, and the sleeve is constructed from steel for durability under high-speed, high-torque conditions. Through-coolant capability allows cutting fluid to pass directly to the tool tip, supporting chip evacuation and thermal management during demanding cutting operations. Installation is performed by qualified machine tool technicians or toolroom personnel.

This sleeve is suited for use in production machining cells running milling, drilling, or reaming operations where hydraulic chucking systems are already in place. The sealed sleeve type is appropriate for applications where coolant containment and tool runout control are critical. It is a direct-fit accessory component for compatible hydraulic chuck bodies requiring a 0.5 inch bore sleeve. Typical environments include aerospace, automotive, and general metalworking shops operating CNC machining centers.

Key Features

• 0.5 inch inside diameter for precise tool shank engagement
• 1.1811 inch head diameter for proper seating in compatible hydraulic chuck bodies
• Sealed sleeve type supports coolant containment and controlled hydraulic clamping
• Through-coolant design channels cutting fluid directly to the cutting zone
• Steel construction withstands high clamping pressures and repeated use cycles
• Rated operating pressure of 150 psi

Compatibility

Designed as an OEM-style replacement or accessory sleeve for hydraulic chuck toolholding systems requiring a 0.5 inch bore sealed sleeve with through-coolant capability.

Installation Notes

Installation should be performed by a qualified machine tool technician or toolroom specialist. Ensure the hydraulic chuck body is fully depressurized and the spindle is locked before inserting or removing the sleeve. Use clean, lint-free wiping cloths to remove debris from mating surfaces prior to assembly, as contamination can affect clamping accuracy. Verify sleeve seating and runout with a dial indicator before returning the spindle to service.
