Accupro 1542812 Hydraulic Chuck Sleeve 1/8 in Sealed

Product Description

The ACCUPRO 1542812 is a sealed hydraulic chuck sleeve designed for use with hydraulic toolholding systems in CNC machining operations. It accepts tools with a 1/8 inch inside diameter and fits into hydraulic chucks with a 1/2 inch bore. The sleeve features through-coolant capability, allowing cutting fluid to pass directly to the tool tip for improved chip evacuation and heat management. Constructed from alloy steel, it provides the rigidity and wear resistance required for high-precision milling, drilling, and reaming applications. Installation is performed by machine tool operators and setup technicians working with hydraulic chuck toolholding systems.

This sleeve is suited for use in CNC machining centers where hydraulic chucks are the standard toolholding method. It is appropriate for both light and moderate-duty cutting applications requiring a 1/8 inch shank tool with coolant delivery. The sealed sleeve type prevents contamination from entering the hydraulic expansion zone, maintaining consistent clamping force over time. The 16.5 mm head diameter and 45 mm length under head make it compatible with standard hydraulic chuck body geometries used in production machining environments.

Key Features

• 1/8 inch inside diameter accepts small-shank cutting tools including drills, end mills, and reamers
• Sealed sleeve type protects the hydraulic expansion chamber from coolant and debris ingress
• Through-coolant design delivers cutting fluid directly to the tool tip
• Alloy steel construction provides hardness and dimensional stability under cutting loads
• 16.5 mm head diameter and 45 mm length under head suit standard hydraulic chuck bodies

Compatibility

Listed as a replacement for SKU 37313285. Designed as an OEM-style replacement sleeve for hydraulic chuck toolholding systems requiring a 1/8 inch ID sealed sleeve with through-coolant capability.

Installation Notes

Installation is performed by qualified machine tool operators or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is removed from the spindle before sleeve installation or removal. Clean the chuck bore and sleeve exterior thoroughly before insertion to prevent damage to sealing surfaces. Follow the hydraulic chuck manufacturer torque specifications for the clamping screw when securing the toolholder assembly.
