Accupro ECIL586000MSC Taper Drill Chuck Arbor JT6

Product Description

The ACCUPRO ECIL586000MSC is a taper drill chuck arbor designed to connect a Jacobs Taper 6 (JT6) drill chuck to a straight-shank spindle or tool holder. The arbor features a 5/8-inch straight shank and a JT6 tapered mount, providing a secure mechanical interface between the chuck and the machine spindle. This type of arbor is a standard component in drill press and milling machine setups where a Jacobs taper chuck must be mated to a straight-shank tool holder. Machinists, toolroom technicians, and maintenance professionals install this arbor when setting up drilling operations that require a JT6-compatible chuck assembly.

This arbor is suited for use in drill presses, milling machines, and similar machine tool applications where a JT6 Jacobs taper chuck mount is required. The 5/8-inch straight shank fits standard collet chucks, drill press spindles, and tool holders sized for that diameter. It is commonly used in light to medium-duty drilling applications across manufacturing, toolroom, and maintenance environments. Install scenarios include replacing a worn or damaged arbor or building a new chuck-and-arbor assembly for a specific spindle configuration.

Key Features

• JT6 Jacobs Taper mount provides a positive, self-holding taper connection to compatible drill chucks
• 5/8-inch straight shank diameter for use with matching spindles or tool holders
• Compact and lightweight at 0.35 pounds, minimizing added mass in the spindle assembly
• Straight shank design allows straightforward insertion and retention in standard drill press spindles
• Single-piece arbor construction for reliable torque transfer between chuck and spindle

Compatibility

Designed as an OEM-style replacement or new-build arbor for machine tool setups requiring a JT6 Jacobs Taper chuck mount with a 5/8-inch straight shank interface.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with machine tool arbor and chuck assembly. Power down and lockout/tagout the machine before installing or removing any chuck arbor. The JT6 taper is seated by pressing the chuck firmly onto the arbor taper; removal typically requires a chuck removal wedge or drift to break the taper seat. Do not hammer directly on the chuck body or arbor threads during installation or removal.
