Sandvik Coromant 5760304 Hydraulic Chuck Sleeve 8mm

Product Description

The SANDVIK COROMANT 5760304 is a hydraulic chuck sleeve designed for use with hydraulic toolholding systems in CNC machining applications. This sleeve features an 8 mm (0.3150 inch) inside diameter and a 20 mm (0.7874 inch) outside diameter, with a 25 mm (0.9843 inch) head diameter and a length under head of 1.9685 inches (50 mm). Constructed from steel, it supports coolant-through delivery at up to 80 psi, making it suitable for deep-bore drilling, reaming, and other precision cutting operations where thermal management and chip evacuation are critical. It is installed by machinists and CNC tooling technicians.

This hydraulic chuck sleeve is used in precision machining environments where consistent gripping force and minimal runout are required. Typical applications include high-speed milling, drilling, and boring operations in both production and job-shop settings. The coolant-through design directs cutting fluid directly to the tool tip, improving tool life and surface finish in ferrous and non-ferrous materials. It is suited for use in machining centers where hydraulic chucks are the preferred workholding method for balanced, vibration-dampened cutting.

Key Features

• 8 mm inside diameter for precise tool engagement in hydraulic chuck systems
• Coolant-through capability supports direct delivery of cutting fluid to the cutting zone
• Steel construction provides durability under high clamping pressures
• 25 mm head diameter and 1.9685 inch length under head for compatible chuck fitment
• Rated for coolant-through use at up to 80 psi

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck toolholding systems accepting an 8 mm bore sleeve with a 20 mm outside diameter and 25 mm head diameter.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machinists. The machine spindle must be fully powered down and the hydraulic chuck pressure released before removing or installing sleeve components. Use manufacturer-specified hydraulic chuck tools and follow shop torque and clamping procedures appropriate to the chuck model in use. Do not exceed the rated coolant pressure for the sleeve or connected toolholding assembly.
