Accupro EJ03200000MSC Taper Drill Chuck Arbor JT2 3MT

Product Description

The ACCUPRO EJ03200000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 2 (JT2) chuck mount to a No. 3 Morse Taper (3MT) machine spindle. This arbor serves as the mechanical interface between the drill chuck and the spindle bore of a drill press, milling machine, or lathe tailstock. The overall length is approximately 4.96 inches (126 millimeters). Weighing 0.66 pounds, the arbor provides a solid, secure fit when seated properly into the spindle. Machinists and tool-and-die technicians are the primary installers of this type of tooling component.

This arbor is suited for use in shop environments running equipment with a No. 3 Morse Taper spindle that requires a JT2 chuck mounting interface. Typical applications include drill press setups in job shops, maintenance facilities, and production environments where standard taper-to-taper arbor connections are used. The Morse taper shank seats directly into the machine spindle, while the Jacobs taper end accepts a compatible JT2 drill chuck.

Compatibility

Designed as an OEM-style replacement or standard tooling arbor for machines equipped with a No. 3 Morse Taper spindle and requiring a JT2 chuck mount interface.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Before seating or removing the arbor, ensure the machine is powered down and the spindle is fully stopped. Clean both the spindle bore and the Morse taper shank thoroughly before insertion to ensure full, even contact and proper seating. Use a drift key and mallet to remove the arbor from the spindle; never pry against the chuck body or spindle face.
