Accupro ECIL012000MSC Taper Drill Chuck Arbor JT2

Product Description

The ACCUPRO ECIL012000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 2 (JT2) drill chuck to a straight-shank machine spindle. The arbor features a 1-inch straight shank diameter and a shank length of 3 inches, providing a rigid, concentric interface between the chuck and the machine. This type of arbor is a standard accessory in machine shop and industrial drilling setups, installed by machinists and tool and die technicians on drill presses, milling machines, and similar equipment where JT2-compatible chucks are used.

This arbor is suited for use in machine shop environments requiring a JT2 chuck mount with a straight-shank spindle interface. It is appropriate for both light and moderate drilling applications on drill presses or vertical milling machines. The straight shank design allows secure clamping in collet chucks or drill press spindles accepting a 1-inch shank. This is a per-unit replacement or setup component commonly sourced for production and maintenance tooling inventories.

Key Features

• JT2 Jacobs Taper mount for direct chuck attachment without fasteners
• 1-inch straight shank diameter for broad machine spindle compatibility
• 3-inch shank length provides clearance and reach in standard setups
• Straight shank design compatible with collet-style and direct-grip spindle holders
• Compact weight of 0.75 pounds reduces spindle load in sensitive setups

Compatibility

Designed as an OEM-style replacement or setup arbor for drill presses and milling machines accepting a JT2 Jacobs Taper chuck mount with a 1-inch straight shank spindle interface.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered off and the spindle fully stopped before handling. The JT2 taper should be cleaned and inspected for burrs or damage before seating the chuck to ensure full contact and concentricity. Use a soft mallet to seat the taper firmly; do not use excessive force that could damage the chuck or arbor bore. Follow applicable shop safety procedures and machine manufacturer guidelines when changing tooling.
