Value Collection 214-8045 MT4 MT5 Reducing Sleeve

Product Description

The VALUE COLLECTION 214-8045 is a standard Morse taper reducing sleeve designed to adapt an MT5 spindle or socket to accept MT4 tooling. The sleeve features a soft body with a hardened tang, which transfers drive force and allows positive ejection of tooling from the spindle. With an overall length of 171 millimeters and a body diameter of 45.5 millimeters, this sleeve fits standard machine tool spindles and is used by machinists and tool-room technicians on lathes, drill presses, and milling machines that use Morse taper tooling systems.

This reducing sleeve is suited for production and maintenance machine shops where MT4 tooling such as drill chucks, end mill holders, and live centers must be used in an MT5 spindle. The 3/4 inch projection keeps the tool positioned correctly relative to the spindle face. It is a direct-fit, no-modification solution for shops running mixed Morse taper tooling across multiple machines.

Key Features

• MT4 inside taper accepts standard MT4 tooling shanks
• MT5 outside taper seats directly into MT5 spindles and sockets
• Soft body with hardened tang for positive drive and clean ejection
• 3/4 inch projection for correct tool positioning at the spindle face
• 171 millimeter overall length suits standard machine tool clearance requirements
• 45.5 millimeter body diameter sized for MT5 socket fitment

Compatibility

Designed as a standard OEM-style reducing sleeve for machine tools with MT5 spindles requiring MT4 tooling adaption. No specific model compatibility data was provided in the product information.

Installation Notes

Installation is performed by machinists or tool-room technicians. Power down and lock out the machine spindle before inserting or removing any taper tooling. Clean both the sleeve taper and the spindle socket thoroughly before seating to prevent fretting and ensure full taper contact. Use a drift and the hardened tang to eject the sleeve cleanly without damaging the spindle bore.
