Accupro ECIL342000MSC Taper Drill Chuck Arbor JT2 3/4 in

Product Description

The ACCUPRO ECIL342000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 2 (JT2) drill chuck to a straight-shank spindle or tool holder. The arbor features a 3/4-inch straight shank and a JT2 tapered mount, providing a secure mechanical interface between the chuck body and the machine spindle. This type of arbor is a standard component in drill press, milling, and lathe setups where a removable chuck connection is required. It is installed by machinists, toolroom technicians, and maintenance trades working with benchtop or floor-standing drill presses.

This arbor is suited for light to medium-duty drilling applications in shop, maintenance, and production environments. The JT2 taper mount is one of the most common Jacobs Taper sizes, widely used on drill presses and milling machine quills with chucks in the 3/8-inch to 1/2-inch capacity range. The straight 3/4-inch shank seats directly into a compatible spindle bore or chuck. It ships as a single unit, making it a practical replacement or spare component for an existing tool setup.

Key Features

• JT2 tapered mount accepts standard Jacobs Taper 2 drill chucks
• 3/4-inch straight shank diameter for direct spindle or holder insertion
• Compact and lightweight at 0.44 pounds
• Single-piece arbor construction provides a rigid chuck-to-spindle connection
• UNSPSC Code 27112800 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or direct-fit arbor for drill presses and machine spindles that accept a 3/4-inch straight shank and mate with JT2 Jacobs Taper drill chucks.

Installation Notes

Installation is performed by machinists or tool technicians. Power down and lock out the machine before seating or removing the arbor. The JT2 taper should be cleaned and free of burrs or debris before pressing the chuck onto the arbor. A chuck removal wedge or arbor drift is the standard tool for separating the chuck from the arbor without damaging either component.
