Kennametal 1093569 Hydraulic Chuck Sleeve 3/8 in Id

Product Description

The KENNAMETAL 1093569 is a slotted hydraulic chuck sleeve designed to adapt tool shanks within hydraulic chuck toolholding systems. It seats between the chuck body and the cutting tool shank, transmitting clamping force while maintaining concentricity under high-speed cutting conditions. The sleeve features a through-coolant design, allowing coolant delivery directly to the cutting zone. Key dimensions are a 3/8 inch inside diameter, 0.787 inch outside diameter, and a head diameter of 0.984 inch. Constructed from steel, this sleeve is built to withstand the clamping pressures typical of hydraulic toolholding applications. Installation and replacement are performed by machinists and toolroom technicians during toolholder setup and maintenance.

This sleeve is suited for CNC machining centers and milling applications where hydraulic chuck toolholders are used. The slotted sleeve design accommodates standard cylindrical shank tools with a 3/8 inch shank diameter. The through-coolant feature supports high-efficiency metal cutting operations where direct coolant delivery to the cutting edge is required. It is used in both production and job-shop environments where consistent tool runout and secure clamping are critical to part quality and tool life.

Key Features

• Steel construction provides durability under sustained hydraulic clamping pressure up to 1500 psi
• 0.984 inch head diameter and 1.969 inch length under head for precise chuck fitment
• Sold individually, compatible with hydraulic chuck toolholding systems requiring this sleeve profile

Compatibility

Designed as an OEM-style replacement or setup component for hydraulic chuck toolholding systems that accept slotted sleeves with a 3/8 inch bore and 0.787 inch outside diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel familiar with hydraulic chuck systems. The toolholder must be fully depressurized and removed from the spindle before inserting or removing the sleeve. Ensure the sleeve bore and tool shank are clean and free of chips or contaminants before assembly, as debris will compromise clamping force and runout. Follow the toolholder manufacturer specifications for clamping pressure and torque when pressurizing the hydraulic chuck body.
