Accupro EJ23300000MSC Taper Drill Chuck Arbor JT33 2MT

Product Description

The ACCUPRO EJ23300000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 33 (JT33) drill chuck to a No. 2 Morse Taper (2MT) spindle. This arbor serves as the mechanical interface between the chuck and the machine spindle, transferring torque and maintaining concentricity during drilling operations. It is used in drill presses, milling machines, and lathes equipped with a 2MT spindle socket. Machinists and tool-and-die professionals install this type of arbor when mounting or replacing drill chucks on compatible machine tools. Weighing 0.35 pounds, the part is compact and straightforward to fit.

This arbor is suited for shop environments where a JT33 chuck must be seated onto a 2MT machine spindle. Typical applications include benchtop and floor-standing drill presses in jobbing shops, maintenance facilities, and production environments. The tapered shank seats firmly into the spindle socket using a draw bar or press fit, and the JT33 mount accepts any standard JT33-compatible drill chuck. Installation requires no special tooling beyond a soft mallet or arbor press and a drift key for removal.

Key Features

• JT33 mount taper accepts standard Jacobs Taper 33 drill chucks
• No. 2 Morse Taper shank fits 2MT spindle sockets on drill presses, mills, and lathes
• Compact form factor at 0.35 pounds for easy handling and storage
• Single-piece arbor construction provides a direct, rigid chuck-to-spindle connection

Compatibility

Designed as a direct-fit arbor for machine tools with a No. 2 Morse Taper spindle socket and drill chucks with a JT33 mount interface.

Installation Notes

Installation is performed by qualified machinists familiar with taper-fit tooling. Clean both the 2MT shank and the spindle socket thoroughly before seating to ensure full taper contact and prevent fretting. Use a soft mallet or arbor press to fully seat the shank; never force the taper with steel-faced tools that could damage the seating surfaces. To remove, use the appropriate drift key through the spindle drift slot and strike with a controlled mallet blow.
