Accupro EJ13300000MSC Taper Drill Chuck Arbor JT33 1MT

Product Description

The ACCUPRO EJ13300000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 33 (JT33) drill chuck to a No. 1 Morse Taper (1MT) spindle. The arbor transfers the tapered press fit of the chuck mount to the machine spindle, providing a secure, concentric interface for drilling operations. At 0.22 pounds, it is a compact, lightweight component suited for benchtop drill presses, milling machines, and similar spindle-driven equipment. Machinists and tool room technicians install this arbor when mounting or replacing a JT33-bore chuck onto a 1MT-taper spindle without the need for a drawbar on most press-fit applications.

This arbor is appropriate for light-duty to general-purpose drilling setups in job shops, maintenance environments, and production settings where a 1MT spindle is present. It seats into the machine spindle via the Morse taper shank and accepts a JT33 chuck on the mount end. Typical applications include vertical drill presses and light milling attachments running twist drills, step drills, or similar tooling. Installation does not require a drawbar on standard press-fit 1MT spindles, though application requirements should be confirmed before use.

Key Features

• JT33 mount taper interfaces directly with Jacobs Taper 33 bore drill chucks
• No. 1 Morse Taper shank seats into standard 1MT machine spindles
• Lightweight construction at 0.22 pounds for easy handling during chuck changes
• Press-fit tapered connection on both ends for concentric, repeatable chuck seating
• Compact form factor suited for benchtop and floor-model drill presses

Compatibility

Designed as an OEM-style replacement arbor for machines equipped with a No. 1 Morse Taper spindle that require a JT33 chuck mount interface.

Installation Notes

A licensed machinist or qualified tool room technician should perform chuck arbor installation. Power down and de-energize the machine before seating or removing the arbor. Clean both the spindle taper bore and the arbor shank thoroughly before pressing the arbor into the spindle to ensure full contact and concentricity. To remove a press-fit Morse taper arbor, use a proper drift key through the spindle drift slot — do not strike the chuck or arbor body directly.
