Sandvik Coromant 5760258 Hydraulic Chuck Sleeve

Product Description

The SANDVIK COROMANT 5760258 is a hydraulic chuck sleeve designed for use with hydraulic toolholding systems in CNC machining applications. It features a 16 mm (0.6299 inches) inside diameter, a 20 mm (0.7874 inches) outside diameter, and a 25 mm (0.9843 inches) head diameter. The length under head measures 50 mm (1.9685 inches). Constructed from steel, this sleeve provides the dimensional precision and rigidity required for accurate tool clamping. Through-coolant capability is built in, allowing cutting fluid delivery directly to the cutting zone. Installed by machinists and toolroom technicians, this sleeve is a direct-fit component within compatible hydraulic chuck assemblies.

This sleeve is suited for precision metal cutting operations in both production and job-shop environments. It fits into hydraulic chuck bodies where a 16 mm bore reduction or adaptation is required. Through-coolant support makes it appropriate for deep-hole drilling, reaming, and other operations where chip evacuation and thermal management at the tool tip are critical. The steel construction holds up to the clamping pressures generated by hydraulic expansion chucks during high-speed or high-feed machining.

Key Features

• 16 mm inside diameter and 20 mm outside diameter for precise sleeve-to-chuck fitment
• 25 mm head diameter provides a positive stop and secure seating surface
• 1.9685 inches (50 mm) length under head accommodates standard reach requirements
• Through-coolant design delivers cutting fluid directly to the tool tip
• Steel construction withstands hydraulic clamping pressure and machining loads
• 80 psi rated pressure specification supports reliable hydraulic actuation

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck toolholding systems requiring a 16 mm bore sleeve with a 20 mm outside diameter interface.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle locked before handling any toolholder components. Verify that the sleeve bore, outside diameter, and head diameter match the hydraulic chuck body specifications before assembly. Do not force the sleeve into the chuck body; confirm seating is flush and secure before applying hydraulic clamping pressure. Inspect coolant passages for obstructions prior to returning the assembly to service.
