Sandvik Coromant 6426580 Hydraulic Chuck Sleeve

Product Description

The SANDVIK COROMANT 6426580 is a hydraulic chuck sleeve designed for use with hydraulic toolholding systems in CNC machining operations. It accepts a 0.5-inch inner diameter shank and features a head diameter of 1.7323 inches with a length under head of 2.7559 inches. Constructed from steel, this sleeve is rated for coolant-through operation at up to 150 psi, allowing cutting fluid to be delivered directly to the tool tip. It is installed by toolroom technicians and CNC setup personnel as part of a precision hydraulic chuck assembly.

This sleeve is suited for use in high-precision milling, drilling, and reaming applications where secure tool clamping and coolant delivery are required. Coolant-through capability makes it appropriate for deep-hole operations or applications where heat management at the cutting zone is critical. The steel construction supports the clamping pressures typical of hydraulic chuck systems used in production machining environments.

Key Features

• 0.5-inch inner diameter accommodates standard half-inch shank tooling
• Coolant-through design rated to 150 psi for direct tip cooling
• 1.7323-inch head diameter for positive seating in hydraulic chuck bodies
• 2.7559-inch length under head suits standard reach requirements
• Steel construction provides durability under repeated clamping cycles

Compatibility

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

Installation Notes

Installation is performed by qualified toolroom or CNC setup personnel. Power down and de-energize the machine spindle before handling any toolholding components. Ensure the hydraulic chuck body is depressurized before inserting or removing the sleeve. Follow the machine tool and chuck manufacturer guidelines for clamping pressure specifications and maintenance intervals.
