Accupro CR03200000MSC MT2 MT3 Morse Taper Reducing Sleeve

Product Description

The ACCUPRO CR03200000MSC is a standard Morse taper reducing sleeve designed to adapt an MT2 inside taper to an MT3 outside taper. It allows tools with an MT2 shank to be mounted in spindles or sockets that accept MT3 tapers. The sleeve is hardened and ground throughout for precise fit and long service life. It measures 4.375 inches overall length with a 0.75 inch projection, and weighs 0.42 pounds. Machinists and tool room technicians use this sleeve to maximize tooling compatibility without changing spindle tooling setups.

This reducing sleeve is used in machine shop and tool room environments where drill presses, lathes, milling machines, or boring machines require taper-to-taper adaptation. It suits applications where an MT2 tool shank must seat securely in an MT3 spindle bore. The hardened and ground finish ensures consistent taper contact and concentricity, which is critical for drilling, reaming, and light milling operations that depend on accurate tool runout.

Key Features

• MT2 inside taper accepts standard MT2-shank tooling
• MT3 outside taper fits MT3 spindle sockets
• Hardened and ground throughout for precise fit and durability
• 0.75 inch projection for standard sleeve clearance
• 4.375 inches overall length suits common spindle depths
• Compact at 0.42 pounds for easy handling and storage

Compatibility

Designed as a standard OEM-style reducing sleeve for machine tools with MT3 spindle tapers requiring MT2-shank tooling adaptation.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Power down and lock out the machine before inserting or removing the sleeve. Clean both the spindle bore and sleeve taper surfaces thoroughly before seating to ensure full contact and prevent fretting. Use a proper drift and drift slot to eject the sleeve cleanly without damaging the taper surfaces.
