Jet jt9-561766 Arbor MT2 X JT3

Product Description

The JET jt9-561766 is a Morse Taper 2 to Jacobs Taper 3 arbor designed for use with JET drill presses and similar benchtop or floor-standing drilling equipment. This arbor serves as the mechanical adapter between the spindle and the drill chuck, transmitting torque from the machine to the cutting tool. It is a direct OEM replacement part for JET power tool assemblies where the spindle accepts an MT2 shank and the chuck requires a JT3 mounting interface. Installation is straightforward and is typically performed by a machinist, tool-and-die technician, or experienced maintenance professional during chuck replacement or press reconditioning.

This arbor is suited for benchtop and floor-standing drill press applications in machine shops, manufacturing facilities, and maintenance environments. It bridges an MT2 spindle taper to a JT3 chuck interface, making it the correct replacement when the original arbor is worn, damaged, or lost. Because it is listed as a JET OEM accessory part, it is intended for use in JET drill press models that share this spindle and chuck taper combination.

Installation Notes

Installation of this arbor should be performed by a qualified technician or machinist. Before beginning, power down and lock out the drill press at the main disconnect in accordance with OSHA lockout/tagout procedures. The arbor shank should be clean and free of burrs before seating it into the spindle taper; use a soft mallet or drift to seat or remove the arbor, never apply side force to the quill assembly. Inspect the chuck taper bore for wear or damage before pressing the chuck onto the JT3 end.
