Discovery Chuck System
Change jaws.
Not chucks.
On the lathe.
The NOVA Discovery Rapid Change Chuck lets you conveniently swap jaw sets without removing the chuck from the lathe. No screws to chase. No re-centering. No lost momentum.
From the inventors of the original four-jaw self-centering chuck.
Since 1988.
Convenience That Keeps You Turning.
Every feature of Discovery is designed to keep you turning. Change jaw sets quickly and conveniently without removing the chuck from the lathe, so your workflow stays uninterrupted and your focus stays on the project and what you love doing—not the setup.
Built for speed. Aligned for accuracy.
The Discovery Chuck is designed to remove friction from your workflow. Five details that make Discovery the fastest way to move from one project to the next.
Effortless Jaw Changes
Swap jaws without removing a single screw — no more digging dropped hardware out of sawdust.
Secure, Confident Locking
The clamp-and-turn mechanism retains screws and holds jaws firm — steady footing for beginners and pros alike.
Side-Mounted Clamping Locks
Ergonomic access from the side of the chuck — better visibility and control than reaching across the face.
Self-Aligning Technology
Every jaw closes true and square by aligning the guide points. No fiddling, no re-mounting, no second-guessing your centering.
Conventional chucks rely on the scroll to equalize jaw position before the mounting screws are tightened. Discovery's self-aligning interface automatically locates each jaw, eliminating the need for manual alignment.
Wider Jaw Compatibility
With nothing protruding from the front face, Discovery opens the door to more jaw shapes and styles than ever.
A Perfect Companion
Discovery isn't here to replace your favorite NOVA chuck — it's another tool in your workshop. Run them side by side: one dialed in for your go-to setup, the other ready whenever you want to discover more. Together, they expand your choices while easing your workflow.
Start Simple. Grow Naturally.
You don't have to predict every project you'll ever make. Begin with the Discovery jaw range today, expand into new holding solutions tomorrow — and with the Discovery adaptor, tap into NOVA's entire classic jaw range whenever you need it. Less time spent on setup means more time spent on the craft.
Seven to Start. No Limit Ahead.
Discovery launches with the seven jaw sets below—but its unobstructed front-face design keeps the range expanding: new shapes, styles, and specialized solutions for more projects and new techniques, with confidence. If there's a jaw you wish existed, we want to hear about it.
