Value Collection 214-8156 MT5 MT6 Reducing Sleeve

Product Description

The VALUE COLLECTION 214-8156 is a standard Morse taper reducing sleeve designed to adapt an MT6 spindle or socket to accept MT5 tooling. Hardened and ground throughout, the sleeve provides a rigid, accurate fit between machine spindle and tool shank. With a 3/8 inch projection and a 63 mm body diameter, this sleeve is sized for heavy-duty machine tool applications. Overall length is 218 mm. Machinists and tool room technicians install this sleeve directly into the machine spindle to step down the taper size without modifying the machine or the tooling. At 5.75 pounds, the part is built for stability under load.

This reducing sleeve is used in machine shop environments where a drill press, milling machine, lathe, or boring machine has an MT6 spindle but the cutting tool or drill chuck carries an MT5 shank. Typical applications include production machining, toolroom work, and maintenance operations requiring taper-to-taper adaptation. It is suited for both manual and CNC machine tools that use standard Morse taper interfaces.

Key Features

• MT5 inside taper accepts standard MT5 tool shanks
• MT6 outside taper seats directly into MT6 machine spindles
• Hardened and ground throughout for dimensional accuracy and wear resistance
• 3/8 inch projection for proper tool seating and ejection
• 63 mm body diameter and 218 mm overall length for MT6-class rigidity
• Weighs 5.75 pounds, indicating solid steel construction suitable for heavy cuts

Compatibility

Designed as a standard OEM-style reducing sleeve for machine tools with an MT6 spindle socket requiring MT5 tooling compatibility.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Power down and lock out the machine spindle completely before inserting or removing the sleeve. Clean both the spindle bore and the sleeve taper with a lint-free cloth to remove oil, chips, or debris before seating, as contamination will affect concentricity and holding force. Use the drift slot and a proper drift key to eject the sleeve safely — never strike the tooling directly to dislodge it.
