Kennametal 1093498 Hydraulic Chuck Sleeve 5/16 in Id

Product Description

The KENNAMETAL 1093498 is a slotted hydraulic chuck sleeve designed for use with hydraulic toolholding systems in precision machining operations. It features a 5/16 inch (0.3125 inch decimal) inside diameter and a 3/4 inch (0.7500 inch decimal) outside diameter, with a head diameter of 0.9840 inches and a length under head of 1.9690 inches. Constructed from steel, this sleeve is rated for 1500 psi operating pressure and includes through-coolant capability to deliver cutting fluid directly to the tool tip. It is installed by machinists and toolroom technicians working with hydraulic chuck systems on CNC machining centers and similar equipment.

This sleeve fits hydraulic chuck bodies that accept a 3/4 inch OD sleeve with a 5/16 inch tool bore. The slotted sleeve design allows the hydraulic expansion mechanism to grip the cutting tool shank evenly and securely. Through-coolant support makes it suitable for deep-hole drilling, reaming, and other operations where direct coolant delivery to the cutting zone is required. It is appropriate for both production and job-shop environments running small-diameter tooling on vertical or horizontal machining centers.

Key Features

• 5/16 inch (7.94 mm) inside diameter for small-shank cutting tools
• 3/4 inch (19.05 mm) outside diameter for standard hydraulic chuck body fitment
• Head diameter of 0.9840 inches (25.00 mm)
• Length under head of 1.9690 inches (50.00 mm)
• Through-coolant design for direct cutting fluid delivery to the tool
• Slotted sleeve construction for uniform hydraulic clamping force
• Steel construction rated to 1500 psi operating pressure

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck bodies requiring a 3/4 inch OD sleeve with a 5/16 inch tool bore and through-coolant capability.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with hydraulic chuck systems. Relieve hydraulic pressure in the chuck body completely before removing or inserting the sleeve. Inspect the sleeve bore and the chuck body bore for contamination or damage before assembly. Follow the chuck manufacturer torque and pressure specifications when pressurizing the hydraulic clamping mechanism after sleeve installation.
