A real time saver, this chuck makes fast work of mounting workpieces or switching jaws. To secure the work, it operates much like a keyless drill chuck; turning the housing by hand quickly tightens the jaws to grip the project, with only the final tightening done with the supplied chuck key. Jaw changes are also simplified, as there are no mounting screws to remove and replace. Insert the included jaw key with a light push to unlock each jaw; you can then remove it by hand and slide in another jaw, which locks in position with an audible click.

Largely made of hardened steel, the 4" diameter chuck weighs just over 5 lb and threads directly onto lathes with a 1" × 8 tpi spindle (an optional 1 1/4" × 8 tpi spindle adapter is available separately). It comes with a set of 1 3/8" nickel-plated steel dovetail jaws; optional jaw sets are also available separately.

Made in USA.
