Kennametal 1093497 Hydraulic Chuck Sleeve Steel

Product Description

The KENNAMETAL 1093497 is a slotted hydraulic chuck sleeve designed to adapt tool shanks within hydraulic chuck toolholding systems. It provides a precision-fit interface between the chuck body and the cutting tool, transmitting clamping force evenly across the tool shank. The sleeve features coolant-through capability, allowing pressurized coolant to reach the cutting zone directly. Constructed from steel, it is built to withstand the clamping pressures common in CNC milling and machining center applications. With a 0.25-inch inside diameter and a 0.75-inch outside diameter, it is sized for small-diameter tooling in high-precision setups. Licensed machinists and toolroom technicians are the primary installers.

This sleeve is intended for use in hydraulic chuck toolholders on CNC machining centers and milling machines where coolant-through capability is required. The slotted sleeve design allows the hydraulic chuck to generate uniform radial clamping pressure around the tool shank. It suits production environments where consistent runout and secure tool retention are critical, particularly in high-speed or tight-tolerance operations. The coolant-through feature supports through-spindle coolant delivery systems commonly found in modern CNC equipment.

Key Features

• Coolant-through design supports direct coolant delivery to the cutting zone
• Slotted sleeve type enables uniform hydraulic clamping pressure distribution
• 0.25-inch inside diameter accommodates small-diameter tool shanks
• 0.75-inch outside diameter with 0.984-inch head diameter for positive chuck registration
• 1.969-inch length under head provides adequate engagement depth within the chuck body
• Steel construction for durability under sustained clamping pressure up to 1500 psi

Compatibility

Designed as an OEM-style replacement or supplemental sleeve for hydraulic chuck toolholding systems accepting a 0.25-inch bore sleeve with a 0.75-inch outside diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with hydraulic chuck systems. Ensure the chuck body and sleeve bore are clean and free of chips or debris before inserting the sleeve. Do not exceed the rated hydraulic clamping pressure of the chuck system. Verify coolant-through port alignment with the chuck body passages before securing the toolholder assembly in the spindle.
