Accupro ECIL346000MSC Taper Drill Chuck Arbor JT6 3/4 Inch

Product Description

The ACCUPRO ECIL346000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 6 (JT6) drill chuck to a straight-shank spindle or toolholder. It features a 3/4-inch straight shank and a JT6 tapered mount, providing a secure, concentric interface between the chuck and the machine spindle. This arbor is used in drilling operations where a JT6-mount chuck must be paired with a 3/4-inch straight-shank holder. Machinists and toolroom technicians install this component as part of drill chuck assemblies on drill presses, milling machines, and similar machine tools. The part weighs 0.53 pounds, making it a compact, lightweight toolholding component.

This arbor is suited for use in machine shop, maintenance, and production drilling environments. It is appropriate for both light-duty and general-purpose drilling setups where a JT6 chuck mount is required with a straight 3/4-inch shank. Typical installations include bench-top and floor-standing drill presses as well as vertical milling machine spindles configured for straight-shank toolholding. Technicians select this arbor when retrofitting or assembling drill chuck setups that require the JT6 taper interface.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before installing or removing the arbor, ensure the machine spindle is fully de-energized and the machine is locked out per applicable safety procedures. The JT6 taper should be seated firmly by pressing or lightly tapping the chuck onto the arbor before mounting the assembly in the spindle. Do not use excessive force that could damage the taper seat or the chuck body.
