Accupro CRS210000 Morse Taper Reducing Sleeve MT1 MT2

Product Description

The ACCUPRO CRS210000 is a standard Morse taper reducing sleeve designed to adapt an MT1 inside taper to an MT2 outside taper on drill presses, lathes, and milling machines. The sleeve features a soft body with a hardened tang, providing the durability needed for repeated tool changes while remaining machinable if trimming is required. With an overall length of 3-7/8 inches and a 5/8-inch projection, this sleeve fits standard spindle bores and tool holders in common machine shop configurations. It weighs 0.22 pounds. Machinists and toolroom technicians use this sleeve to run MT1-shank tooling in MT2-taper spindles without adapter plates or custom fixtures.

This reducing sleeve is suited for use in manual and CNC machine tools equipped with an MT2 spindle bore, including benchtop and floor-standing drill presses, engine lathes, and milling machines. It accepts any MT1-shank tooling such as drill chucks, center drills, and step drills. The hardened tang engages the spindle drift slot for secure seating and clean removal. It is appropriate for light to medium-duty cutting operations in job shop, maintenance, and production environments.

Compatibility

Designed as a standard OEM-style reducing sleeve for machine tool spindles with an MT2 bore requiring MT1-shank tooling adaption.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before inserting or removing the sleeve. Clean the spindle bore and sleeve taper surfaces thoroughly before seating to ensure full contact and concentricity. Use a proper drift bar and mallet against the tang to eject the sleeve; never strike the tooling or chuck directly.
