Value Collection 214-8124 MT2 Inside MT4 Outside Reducing Sleeve

Product Description

The VALUE COLLECTION 214-8124 is a standard Morse taper reducing sleeve designed to adapt an MT2 inside taper to an MT4 outside taper. Hardened and ground throughout, this sleeve provides a precise, rigid fit between the spindle and tooling. The body measures 30mm in diameter with an overall length of 215mm and a 0.25 inch projection. It is used in machine shops and production environments where a smaller-shank tool or attachment must seat securely in a larger-taper spindle. Machinists and toolroom technicians install this sleeve in drill presses, milling machines, and lathes as a standard workholding accessory.

This reducing sleeve suits applications where MT2 tooling must run in an MT4 spindle without an adapter arbor. Typical use cases include mounting MT2 drill chucks, live centers, or cutting tool holders in machines equipped with MT4 spindle bores. It is appropriate for both production and toolroom settings handling general-purpose drilling, reaming, or turning operations where taper-fit rigidity is required.

Key Features

• MT2 inside taper accepts standard MT2-shank tooling and accessories
• MT4 outside taper seats directly in MT4 spindle bores
• Hardened and ground throughout for dimensional accuracy and long service life
• 30mm body diameter with 215mm overall length for deep spindle engagement
• 0.25 inch projection for controlled tool positioning

Compatibility

Designed as an OEM-style reducing sleeve for machine tool spindles with an MT4 bore requiring MT2 tooling compatibility. Consult your machine tool documentation to confirm taper specifications before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before inserting or removing the sleeve from the spindle bore. Clean both taper surfaces thoroughly to remove oil, chips, and debris before seating the sleeve, as contamination will prevent proper taper engagement and can cause runout. Use a proper drift and dead-blow mallet to remove the sleeve from the spindle when required; never use a steel hammer directly on the sleeve body.
