Value Collection 214-8115 MT1 Inside MT5 Outside Reducing Sleeve

Product Description

The VALUE COLLECTION 214-8115 is a standard Morse taper reducing sleeve designed to adapt an MT1 inside taper to an MT5 outside taper. It allows machinists and toolroom technicians to mount MT1-shank tooling into spindles, tailstocks, or quills that accept an MT5 socket. The sleeve is hardened and ground throughout for precise taper-to-taper contact and consistent tool alignment under load. With a 0.25-inch projection and a 20 mm body diameter, this sleeve fits standard machine tool configurations where a size reduction is required between the spindle and the cutting tool shank.

This reducing sleeve is used in metalworking and machining environments, including manual lathes, milling machines, and drill presses equipped with MT5 spindles or tailstocks. It is suited for production shops, toolrooms, and maintenance departments that need to run smaller MT1 tooling in larger-taper machines without replacing the spindle. The hardened and ground construction supports repeated installation and removal cycles while maintaining dimensional accuracy.

Key Features

• MT1 inside taper accepts MT1-shank drills, reamers, and other tooling
• MT5 outside taper seats directly into MT5 spindle or tailstock sockets
• Hardened and ground throughout for accurate fit and long service life
• 0.25-inch projection for positive tool ejection during removal
• 20 mm body diameter with 232 mm overall length for full taper engagement

Compatibility

Designed as a standard OEM-style reducing sleeve for machine tools equipped with an MT5 spindle or tailstock socket requiring MT1 tooling accommodation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Clean both the MT5 socket and the outside taper of the sleeve thoroughly before seating to prevent fretting and misalignment. Drive the sleeve firmly into the spindle by hand or with a soft mallet to ensure full taper contact. To remove, use the appropriate drift punch against the projection slot with the spindle stationary and all power isolated.
