Accupro EMT2120000MSC Drill Chuck Arbor 1/2-20 2MT Taper

Product Description

The ACCUPRO EMT2120000MSC is a threaded drill chuck arbor designed to connect a drill chuck to a Morse taper spindle. It features a 1/2-20 threaded mount on the chuck end and a No. 2 Morse taper (2MT) shank on the machine end. The overall length is approximately 100 millimeters (roughly 3.94 inches). This arbor serves as the mechanical interface between a drill chuck and a drill press, lathe, or milling machine spindle. It is installed by machinists and tool-and-die trades working with benchtop or floor-standing equipment that accepts 2MT spindle tapers.

This arbor is suited for use in machine shop and industrial maintenance applications where a 1/2-20 threaded chuck must be mounted to a No. 2 Morse taper spindle. Typical installations include drill presses and lathes in production or job-shop environments. The 1/2-20 thread size is a common standard for mid-range drill chucks, making this arbor a practical replacement or spare for shops running multiple machines with 2MT spindle bores.

Compatibility

Designed as an OEM-style replacement arbor for drill presses, lathes, and milling machines equipped with a No. 2 Morse taper spindle bore and requiring a 1/2-20 threaded chuck mount.

Installation Notes

Installation and removal of Morse taper arbors should be performed by a qualified machinist or maintenance technician. Before servicing, power down and lock out the machine at the disconnect switch per OSHA lockout/tagout procedures. The taper shank is seated by firm axial pressure and is released with a drift key through the spindle knockout slot — do not use excessive force that could damage the spindle bore. Inspect both the arbor taper and the spindle bore for nicks or burrs before seating.
