Accupro EJ01100000MSC Taper Drill Chuck Arbor JT1 1MT

Product Description

The ACCUPRO EJ01100000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 1 (JT1) drill chuck to a machine spindle with a No. 1 Morse Taper (1MT) shank. It serves as the mechanical interface between the chuck and the spindle, transmitting torque and maintaining concentricity during drilling operations. The arbor features a tapered shank that seats directly into a 1MT spindle bore and a JT1 mount taper at the opposite end for chuck installation. At an overall length of approximately 3.31 inches (84 mm) and a weight of 0.13 pounds, it is a compact, lightweight component suited for benchtop drill presses and light machining equipment.

This arbor is appropriate for use in machine shop, maintenance, and light production environments where a JT1 chuck must be mounted to a 1MT spindle. Typical applications include benchtop and floor-standing drill presses, milling machine quills fitted with 1MT bores, and similar light-duty metal or woodworking equipment. Machinists and maintenance technicians install this arbor when setting up or replacing drill chuck assemblies on compatible machines.

Installation Notes

Installation is performed by machinists or maintenance technicians. Power down and lock out the machine before seating or removing the arbor. The taper shank should be clean and free of burrs or oil before seating into the spindle bore to ensure proper engagement. Use a drawbar or drift key as appropriate for the spindle design when securing or ejecting the arbor.
