Value Collection 214-8023 MT2 to MT3 Reducing Sleeve

Product Description

The VALUE COLLECTION 214-8023 is a standard Morse taper reducing sleeve designed to adapt an MT2 inside taper to an MT3 outside taper on drill presses, lathes, and milling machines. The sleeve features a soft body with a hardened tang, allowing secure tool holding while enabling easy removal with a drift key. It measures 112mm overall length with a 24.7mm body diameter and a 0.75-inch projection. This type of adapter is a common bench-level shop consumable installed by machinists and tool-room technicians to fit smaller-shank tooling into larger-spindle machines without replacing the tooling itself.

Reducing sleeves like the 214-8023 are used in machine shop environments wherever tooling shank sizes do not match spindle bore sizes. Typical applications include adapting drill chucks, end mill holders, or boring heads with MT2 shanks into MT3 spindles. The sleeve seats directly into the machine spindle and accepts the smaller-taper tool on the inside bore. This makes it a practical, low-cost solution for shops running mixed tooling inventories on standard manual machine tools.

Key Features

• MT2 inside taper accepts standard MT2-shank tooling
• MT3 outside taper seats into MT3 spindle bores
• Soft body with hardened tang for drift-key removal without sleeve damage
• 0.75-inch projection for proper tool engagement and clearance
• 112mm overall length suits standard manual machine spindle depths
• 24.7mm body diameter for stable seating in the spindle bore

Compatibility

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

Installation Notes

Installation is performed by machinists or tool-room technicians. Power down and lock out the machine spindle completely before inserting or removing any taper tooling. Clean both the sleeve exterior taper and the spindle bore with a lint-free cloth to remove oil, chips, or debris before seating the sleeve, as contamination will prevent proper taper engagement. Use a proper drift key inserted through the spindle drift slot to remove the sleeve — never use a hammer directly on the sleeve body.
