Jacobs 7307N Taper Drill Chuck Arbor JT2 2MT

Product Description

The JACOBS 7307N is a taper drill chuck arbor designed to connect a Jacobs Taper 2 (JT2) drill chuck to a No. 2 Morse Taper (2MT) spindle. The arbor serves as the mechanical interface between the chuck and the machine spindle, transmitting torque and maintaining concentricity during drilling operations. Weighing 0.5 pounds, it is a compact, solid component suited for drill presses, lathes, and milling machines equipped with a 2MT spindle bore. Machinists, tool-and-die workers, and maintenance technicians install this arbor when mounting or replacing a JT2-mount chuck on 2MT-equipped machine tools.

This arbor is appropriate for bench-top and floor-standing drill presses, metalworking lathes, and mill-drill machines that use a No. 2 Morse Taper spindle. It accepts any chuck with a JT2 (Jacobs Taper No. 2) mount, making it a standard replacement or retrofit component in machine shop, industrial maintenance, and vocational training environments. It is equally suitable for light production work and general-purpose drilling applications where a reliable chuck-to-spindle connection is required.

Key Features

• JT2 mount taper accepts standard Jacobs Taper No. 2 drill chucks
• No. 2 Morse Taper shank fits widely available 2MT spindle bores
• Compact form factor at 0.5 pounds for easy handling and installation
• Serves as a direct interface between chuck and machine spindle for accurate chuck seating
• UNSPSC Code 27112800 for procurement and catalog classification

Compatibility

Designed for use with JT2-mount drill chucks on machine tools equipped with a No. 2 Morse Taper (2MT) spindle, including drill presses, lathes, and mill-drill machines configured with a 2MT spindle bore.

Installation Notes

A machinist or qualified technician should install this arbor. Before installation, power down and lock out the machine in accordance with applicable OSHA lockout/tagout procedures. Clean both the Morse Taper shank and the spindle bore thoroughly to remove oil, chips, and debris before seating the arbor, as contamination will compromise concentricity and holding force. The Morse Taper is self-holding when properly seated; use a drift key and mallet to remove the arbor from the spindle - do not pry against the chuck body.
