Accupro EJ02100000MSC Taper Drill Chuck Arbor JT1 2MT

Product Description

The ACCUPRO EJ02100000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper No. 1 (JT1) drill chuck to a No. 2 Morse Taper (2MT) spindle. It serves as the mechanical interface between the chuck and the machine spindle, transmitting torque and maintaining concentricity during drilling operations. The arbor has an overall length of approximately 3.98 inches (101 mm) and weighs 0.31 pounds. It is installed by machinists and tool-crib technicians on drill presses, lathes, and milling machines equipped with a 2MT spindle bore.

This arbor is suited for use in machine shops, maintenance facilities, and production environments where a JT1 chuck must be mounted to a 2MT spindle. Typical applications include drill press setups for ferrous and non-ferrous materials, light-duty lathe tailstock drilling, and general-purpose hole-making operations. The Morse Taper shank seats securely in the spindle without fasteners, relying on the self-holding taper geometry for retention during normal cutting loads.

Key Features

• JT1 Jacobs Taper mount accepts standard JT1 drill chucks
• No. 2 Morse Taper (2MT) shank fits 2MT spindle bores on drill presses and lathes
• Overall length of 3.98 inches (101 mm) for correct chuck-to-spindle positioning
• Self-holding Morse Taper geometry provides secure, tool-free spindle retention
• Lightweight at 0.31 pounds for easy handling during chuck changes

Compatibility

Designed as an OEM-style replacement or upgrade arbor for machine spindles with a No. 2 Morse Taper bore and drill chucks with a JT1 Jacobs Taper mount.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Before seating or removing the arbor, power down the machine and engage any spindle lock per the machine manufacturer's procedures. Clean both the 2MT spindle bore and the arbor shank of oil, chips, and burrs before seating to ensure full taper contact. Use a proper drift punch and soft mallet to drive the arbor free when removal is required — do not strike the chuck body directly.
