Jet 561708 Taper Mount Drill Chuck 1/8-5/8 Inch JT-3

Product Description

The JET 561708 is a taper mount drill chuck designed for use on drill presses and milling machines where a Jacobs Taper No. 3 (JT-3) spindle interface is required. It accepts drill bit shanks from 1/8 inch up to 5/8 inch, covering the range commonly needed for metal, wood, and general fabrication work. The chuck mounts directly onto a JT-3 taper arbor and provides secure bit retention through a keyed or keyless mechanism appropriate to the chuck body design. Weighing 2 pounds, it is a solid, shop-grade tool suited for installation by machinists, maintenance technicians, and skilled tradespeople working with stationary drill equipment.

This chuck is intended for stationary drill press and milling machine applications in commercial shops, maintenance facilities, and trade environments. It handles the full range of standard fractional drill bit sizes from 1/8 inch through 5/8 inch, making it appropriate for general-purpose hole-making in metal, wood, plastic, and composite materials. The JT-3 taper mount is a widely used interface on mid-size drill press spindles, making this chuck a practical replacement or upgrade for worn or damaged original equipment chucks.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Disconnect and lock out power to the drill press or milling machine before removing the existing chuck or arbor. The chuck seats onto the JT-3 taper with a firm mallet-driven press fit and is removed using a chuck removal wedge or drift. Do not strike the chuck body directly with a steel hammer, as this can damage the taper bore or chuck jaws.
