Accupro 1542809 Hydraulic Chuck Sleeve 1/2 in Slotted

Product Description

The ACCUPRO 1542809 is a slotted hydraulic chuck sleeve designed to reduce the bore diameter of a hydraulic chuck body, allowing smaller-shank tooling to be held securely in larger chuck systems. Machined from alloy steel, this sleeve features a 1/2-inch inside diameter and a 1-1/4-inch outside diameter, with a head diameter of 39.0 millimeters and a length under head of 60.50 millimeters. The through-coolant design allows cutting fluid to pass directly to the tool tip, supporting higher-speed and deeper-cutting operations where heat and chip evacuation are critical concerns. It is installed by machinists and tool crib technicians on CNC machining centers.

This sleeve is suited for use in precision CNC milling and boring applications where a hydraulic chuck requires a reduction insert to grip 1/2-inch round shank tooling such as end mills, drills, and reamers. The slotted sleeve design is compatible with hydraulic expansion chuck bodies that accept a 1-1/4-inch sleeve outer diameter. It is appropriate for both production shop and job shop environments running ferrous and non-ferrous materials where through-coolant capability is required or preferred.

Key Features

• Slotted sleeve design mates with hydraulic chuck expansion bodies for a secure, vibration-dampening grip
• Through-coolant passage supports direct coolant delivery to the cutting edge
• Alloy steel construction provides strength and dimensional stability under cutting loads
• 1/2-inch inside diameter accepts standard 1/2-inch shank tooling
• 1-1/4-inch outside diameter fits hydraulic chuck bodies with matching bore
• Head diameter of 39.0 millimeters and length under head of 60.50 millimeters for precise fitment

Compatibility

Designed as a replacement reduction sleeve for hydraulic chuck bodies accepting a 1-1/4-inch outside diameter sleeve. This part replaces SKU 37313061.

Installation Notes

Installation is performed by a machinist or tooling technician. Before inserting or removing any chuck sleeve, confirm the spindle is fully stopped and the machine is in a safe, locked-out state per your facility lockout/tagout procedures. Ensure the chuck bore and sleeve exterior are clean and free of chips or burrs before seating the sleeve. Consult the hydraulic chuck manufacturer's torque and clamping specifications for the chuck body in use.
