Kennametal 1093268 Hydraulic Chuck Sleeve 0.5in Id Coolant

Product Description

The KENNAMETAL 1093268 is a hydraulic chuck sleeve designed for use in hydraulic toolholding systems on CNC machining centers and similar precision machine tools. The sleeve fits between the hydraulic chuck body and the cutting tool shank, providing a secure, vibration-dampened grip. This slotted steel sleeve features a 0.5-inch inside diameter, a 0.75-inch outside diameter, and supports coolant-through delivery at up to 1500 psi, making it suitable for deep-hole drilling and high-speed milling operations where direct coolant flow to the cutting edge is required. It is installed by machinists and CNC toolroom technicians.

This sleeve is used in precision metalworking environments including aerospace, automotive, and general manufacturing shops. The coolant-through design channels cutting fluid directly to the tool tip, improving chip evacuation and extending tool life in demanding applications. The slotted sleeve configuration allows the hydraulic expansion zone of the chuck to engage the tool shank evenly. The 1.969-inch length under head and 0.984-inch head diameter are consistent with standard hydraulic chuck sleeve geometry for this bore size. Installation typically occurs during toolholder setup at the machine or in the tool crib.

Key Features

• Coolant-through design supports internal coolant delivery up to 1500 psi
• Slotted sleeve type for uniform hydraulic clamping force distribution
• 0.5-inch inside diameter accommodates 1/2-inch tool shanks
• 0.75-inch outside diameter fits corresponding hydraulic chuck bore
• Steel construction for durability in high-cycle machining environments
• 1.969-inch length under head suits standard hydraulic chuck depth requirements

Compatibility

Designed as an OEM-style replacement or spare hydraulic chuck sleeve for hydraulic toolholding systems requiring a 0.5-inch ID, 0.75-inch OD slotted steel sleeve with coolant-through capability.

Installation Notes

Installation and tool setup should be performed by a qualified machinist or CNC toolroom technician. Ensure the hydraulic chuck and machine spindle are fully depressurized and the machine is locked out before inserting or removing sleeves. Clean the sleeve bore and chuck expansion cavity thoroughly before assembly to prevent contamination that could affect clamping concentricity. Follow the toolholder manufacturer's torque and pressure specifications for the hydraulic chuck actuator.
