Accupro 1534207 Hydraulic Chuck Sleeve 5/16 in Slotted

Product Description

The ACCUPRO 1534207 is a slotted hydraulic chuck sleeve designed to reduce the bore diameter of a hydraulic chuck body, allowing it to grip smaller-shank cutting tools with precision. Built from alloy steel, this sleeve accepts a 5/16-inch inside diameter tool shank and fits into a chuck with a 3/4-inch outside diameter bore. The 24.0 mm head diameter and 50.50 mm length under head make this a compact, purpose-built adapter for machining centers and CNC milling applications. Through-coolant capability allows cutting fluid to pass directly to the tool tip, supporting high-speed or deep-cavity machining operations. Installation and tool changes are handled by machinists and CNC setup technicians.

This sleeve is used in hydraulic chuck toolholding systems found in CNC machining centers, milling machines, and similar metal-cutting equipment. The slotted design accommodates through-coolant flow without sacrificing clamping integrity. It is suited for production environments where consistent tool runout and secure shank retention are required. The 5/16-inch bore makes it appropriate for smaller-diameter end mills, drills, and reamers commonly used in finishing and detail machining operations.

Key Features

• 5/16-inch inside diameter for smaller-shank cutting tool compatibility
• 3/4-inch outside diameter fits standard hydraulic chuck bodies
• Slotted sleeve design supports through-coolant delivery to the tool tip
• Alloy steel construction for rigidity and wear resistance under cutting loads
• 50.50 mm length under head and 24.0 mm head diameter for compact fitment
• Sold individually, MOQ of 1

Compatibility

Designed as an OEM-style replacement sleeve for hydraulic chuck toolholding systems with a 3/4-inch bore that require a 5/16-inch inside diameter reduction.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. The chuck and machine spindle must be fully de-energized and the spindle brought to a complete stop before inserting or removing sleeves. Inspect the sleeve bore and chuck body for burrs or debris before seating the sleeve to ensure proper clamping force and runout. Do not force the sleeve into the chuck body; proper fitment requires clean, undamaged mating surfaces.
