The Pro-Tek Nova G3 is well-suited for mini and midi lathes with up to a 16” swing over the bed. A four-jaw, self-centering scroll chuck, it features high-powered gearing that delivers a tenacious hold. With its minimal body length, it maximizes your distance between centers and reduces weight and stress on smaller lathe spindles. The Pro-Tek model features all the premium performance of its predecessor, plus numerous upgrades like corrosion-resistant nickel plating, improved 50mm jaws with both a dovetail profile and serrations and durable 6-point star fasteners. It’s easy to close with just one hand using the included T-handled hex wrench. Includes a set of 2” (50mm) jaws.

Note: This is an insert chuck, and requires you to purchase a dedicated Insert/Adapter for mounting on your lathe.
