Kennametal 3026651 Hydraulic Chuck Sleeve 6mm Id 20mm Od

Product Description

The KENNAMETAL 3026651 is a hydraulic chuck sleeve designed for use with hydraulic toolholding systems in precision machining operations. This slotted sleeve features a 6 mm (0.2362 inch) inside diameter and a 20 mm (0.7870 inch) outside diameter, with a 25 mm (0.9840 inch) head diameter. The length under head measures 1.969 inches (50 mm). Constructed from steel and rated for 1,500 psi operating pressure, it supports coolant-through delivery to keep cutting tools and workpieces cool during high-speed operations. Machinists and toolroom technicians install this component when adapting smaller-shank tools into hydraulic chucks.

This sleeve is suited for CNC machining centers, milling machines, and similar machine tool platforms where hydraulic chucks are used to hold rotating cutting tools. The coolant-through design directs fluid directly to the cutting zone, which is especially useful in deep-pocket milling, drilling, and reaming applications. The slotted sleeve construction allows for the uniform clamping pressure that hydraulic chucks generate during tool lockup.

Key Features

• 6 mm inside diameter with 0.2362 inch decimal equivalent for precise tool fitment
• Slotted sleeve design works with hydraulic chuck clamping mechanisms
• Coolant-through capability directs cutting fluid to the tool tip
• Rated for 1,500 psi operating pressure
• Steel construction for durability in production machining environments
• 25 mm head diameter with 1.969 inch length under head

Compatibility

Designed as an OEM-style replacement or accessory sleeve for hydraulic chuck toolholders requiring a 6 mm bore sleeve with a 20 mm outside diameter and coolant-through capability.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with hydraulic chuck systems. Ensure the hydraulic chuck is fully released and machine spindle is powered down before inserting or removing any sleeve. Clean the sleeve bore and chuck bore thoroughly before installation to prevent contamination that could affect clamping accuracy. Follow the chuck manufacturer's torque and actuation specifications when locking the hydraulic mechanism.
