Sandvik Coromant 5760296 Hydraulic Chuck Sleeve

Product Description

The SANDVIK COROMANT 5760296 is a hydraulic chuck sleeve designed to adapt smaller-diameter tooling within hydraulic tool-holding systems. It provides a precise bore interface between the cutting tool shank and the hydraulic chuck body, transmitting clamping force uniformly around the tool shank for consistent runout control. The sleeve features a 6 mm inside diameter, a 12 mm outside diameter, and a 16 mm head diameter, with a length under head of 1.5748 inches (40 mm). Coolant-through capability supports internal coolant delivery directly to the cutting zone. Machined from steel for rigidity and durability, this sleeve is installed by machinists and toolroom technicians setting up precision milling, drilling, or reaming operations.

This sleeve is used in CNC machining centers and milling machines wherever a hydraulic chuck requires a reduction sleeve to accept 6 mm shank tooling. It is suited for high-precision applications in production and job-shop environments where runout and tool balance are critical. The coolant-through feature makes it appropriate for deep-hole drilling, high-speed finishing passes, and other operations where directed coolant flow improves tool life and chip evacuation.

Key Features

• 6 mm inside diameter accepts standard 6 mm tool shanks with hydraulic clamping force
• 12 mm outside diameter fits hydraulic chuck bores sized for 12 mm sleeves
• 16 mm head diameter provides a positive axial stop against the chuck face
• Coolant-through design allows internal coolant delivery to the cutting edge
• Steel construction for rigidity and resistance to deformation under clamping pressure
• 80 psi rated pressure supports consistent hydraulic clamping performance

Compatibility

Designed as an OEM-style reduction sleeve for hydraulic chuck systems that accept 12 mm OD sleeves and require a 6 mm ID bore interface.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel familiar with hydraulic chuck systems. Ensure the hydraulic chuck is fully released and machine spindle is powered down before inserting or removing the sleeve. The sleeve and chuck bore should be clean and free of chips or debris before assembly to avoid compromising runout accuracy. Do not exceed the rated hydraulic pressure of the chuck system when clamping.
