Value Collection 214-8123 MT2 to MT3 Reducing Sleeve

Product Description

The VALUE COLLECTION 214-8123 is a standard Morse taper reducing sleeve designed to adapt an MT2 inside taper to an MT3 outside taper on drill presses, lathes, milling machines, and similar machine tool spindles. The sleeve is hardened and ground throughout for dimensional accuracy and long service life under repeated tool changes. With a 30mm body diameter and an overall length of 194mm, this sleeve fits securely in MT3-receiving spindles while accepting MT2-shank tooling such as drill chucks, end mill adapters, and live centers. It is a straightforward shop consumable used by machinists and tool-room technicians to maximize the range of tooling a single spindle can accept.

This reducing sleeve is suited for machine shop and production environments where MT2 tooling must run in an MT3 spindle without a dedicated adapter. Typical applications include drill press columns, lathe tailstock quills, and vertical milling machine spindles configured with an MT3 bore. The 3/4-inch projection allows standard tang-drive ejection with a drift key when removing tooling from the spindle. Both residential and light industrial machine tool setups benefit from this style of sleeve when mixed taper tooling is in use.

Key Features

• MT2 inside taper accepts MT2-shank drills, chucks, and tooling directly
• MT3 outside taper seats into any MT3 spindle bore
• Hardened and ground throughout for accurate taper fit and extended wear life
• 3/4-inch projection for positive drift-key ejection
• 30mm body diameter with 194mm overall length for stable spindle engagement

Compatibility

Designed as a standard OEM-style reducing sleeve for machine tool spindles with an MT3 receiving bore requiring MT2 inside-taper tooling.

Installation Notes

Installation is performed by machinists or qualified machine tool operators. Power off and lockout the machine before inserting or removing the sleeve. Clean the spindle bore and sleeve taper surfaces thoroughly before seating to ensure full taper contact and prevent fretting. Use a proper drift key and drift slot to eject the sleeve cleanly without damaging the spindle bore.
