Jacobs 7367N Taper Drill Chuck Arbor JT3 Mount 1 Inch

Product Description

The JACOBS 7367N is a taper drill chuck arbor designed to mount drill chucks with a JT3 Jacobs taper interface onto drilling machines, drill presses, and similar rotary equipment. It features a straight shank with a 1-inch nominal diameter and an overall length of 4.375 inches, making it a direct-fit adapter between the machine spindle and the chuck body. The 3-inch shank length provides solid engagement in the spindle bore. Machinists, tool-and-die technicians, and maintenance tradespeople install this arbor when setting up or replacing drill chuck assemblies on benchtop or floor-standing drill presses.

This arbor is suited for use in machine shop, maintenance, and light industrial environments where JT3-mount drill chucks are the standard configuration. It is a direct replacement or spare component for drill press setups requiring a straight-shank arbor. The straight shank design is compatible with drill press spindles that accept a 1-inch shank via a drawbar or press-fit retention method. No special tooling beyond standard press or drawbar hardware is required for most installations.

Key Features

• JT3 Jacobs taper mount interfaces directly with JT3-mount drill chucks
• Straight shank at 1-inch nominal diameter for broad spindle compatibility
• 3-inch shank length provides deep, stable spindle engagement
• Overall length of 4.375 inches suits standard drill press spindle depths
• Lightweight at 0.6875 pounds, reducing added load on the spindle assembly

Compatibility

Designed as an OEM-style replacement or upgrade arbor for drill press and rotary machine spindles accepting a 1-inch straight shank and JT3-mount drill chucks. Specific model compatibility was not provided in product data; verify spindle shank bore diameter and chuck taper size before installation.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Disconnect and lock out the drill press from its power source before removing or installing any spindle components. Ensure the spindle bore and arbor shank are clean and free of burrs before seating the arbor; use a proper drawbar or arbor press as appropriate for the machine design. Never strike the chuck or arbor directly with a steel hammer - use a brass drift or soft mallet if removal force is required.
