Accupro CR05200000MSC MT2 to MT5 Reducing Sleeve

Product Description

The ACCUPRO CR05200000MSC is a standard Morse taper reducing sleeve designed to adapt an MT2 inside taper to an MT5 outside taper. It allows tools or accessories with an MT2 shank to be seated in a spindle or socket bored to MT5. The sleeve is hardened and ground throughout, providing the dimensional accuracy and surface finish required for reliable tool holding in machine shop environments. With an overall length of 6.125 inches and a 0.25 inch projection, it fits standard drill press, lathe, and milling machine setups. Machinists and tool room technicians are the primary installers of this type of adapter.

This reducing sleeve is suited for metalworking applications where a machine spindle carries an MT5 socket and the cutting tool or drill chuck uses an MT2 shank. Typical use cases include adapting smaller-shank twist drills, reamers, and centers into larger-bore spindles on drill presses, lathes, and milling machines. The sleeve eliminates the need for a dedicated MT5-shanked tool when an MT2 tool is already on hand. It is a common shop consumable in production and maintenance machining environments.

Key Features

• MT2 inside taper accepts standard MT2 shank tooling
• MT5 outside taper seats directly into MT5 spindles and sockets
• Hardened and ground throughout for dimensional accuracy and long service life
• 6.125 inch overall length suits standard spindle depths
• 0.25 inch projection for proper tool engagement and drift-slot access

Compatibility

Designed as an OEM-style reducing sleeve for machine tools fitted with an MT5 spindle bore that require use of MT2 shank tooling.

Installation Notes

Installation is performed by machinists or tool room personnel. Power down and lock out the machine before inserting or removing any taper sleeve. Clean the spindle bore and the sleeve's outside taper with a lint-free cloth to remove oil, chips, and debris before seating, as contamination causes misalignment and runout. Remove the sleeve using a drift bar inserted through the spindle drift slot — never attempt to pry or hammer the sleeve from the side.
