Sandvik Coromant 5760290 Hydraulic Chuck Sleeve

Product Description

The SANDVIK COROMANT 5760290 is a sealed hydraulic chuck sleeve designed to reduce tool shank diameter within a hydraulic chuck body. It accepts a 4 mm (0.1575 inches) inside diameter tool shank and presents a 12 mm (0.4724 inches) outside diameter to the chuck bore. The head diameter measures 16 mm (0.6299 inches). Length under head is 1.5748 inches (40 mm). The sleeve is constructed from steel and supports coolant-through delivery, making it suitable for high-precision drilling, reaming, and milling applications where chip evacuation and thermal management are priorities.

This sleeve is used in machining environments where a hydraulic chuck is sized for a 12 mm shank tool but the cutting tool requires a 4 mm collet bore. Typical applications include CNC machining centers and turning centers running precision boring, drilling, or finish milling operations. The sealed sleeve design maintains hydraulic clamping pressure integrity while the coolant-through feature directs fluid directly to the cutting zone. Installation is performed by qualified machinists or tooling setup technicians in production or job-shop environments.

Key Features

• 4 mm inside diameter accommodates standard 4 mm tool shanks
• 12 mm outside diameter fits hydraulic chuck bores sized for 12 mm shanks
• Sealed sleeve type maintains hydraulic clamping pressure
• Coolant-through design directs cutting fluid to the tool tip
• Steel construction for rigidity and wear resistance
• 16 mm head diameter provides positive axial seating in the chuck

Compatibility

Designed for use with hydraulic chuck bodies that accept a 12 mm shank bore, where a 4 mm shank tool is required. Confirm chuck body compatibility and coolant-through port alignment before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before inserting or removing the sleeve. Ensure the chuck bore and sleeve OD are clean and free of debris before seating. Do not exceed the rated hydraulic clamping pressure of 80 units as specified for this sleeve; consult the hydraulic chuck manufacturer documentation for actuation procedure.
