Item #

The SuperNova 2 is a solid, powerful chuck, perfect for use on lathes with up to a 20'' swing. It is offered here in a value package with a set of 12'' Cole Jaws for finishing the bottoms of bowls, plus the Cole Jaw Buffer Kit, which provides a more solid grip on a wide range of vessels. The chuck also includes the standard 2'' jaws, making it an excellent, all-purpose geared chuck. It's packed with exciting, innovative features such as a fully sealed composite indexing backing plate and copper-infused jaw slides. Its patented gearing system delivers incredible gripping power. You'll find yourself turning longer, more delicate stems, as well as larger, rougher work that was difficult to handle before. The SuperNova 2 requires only one hand to operate. Using a ball-nosed hex wrench with a large handle, its easy to tighten. This is an insert chuck, and requires you to purchase a dedicated Insert/Adapter for mounting on your lathe.


  • Fully sealed backing plate is made from ultra-tough Duracon composite, reinforced with stranded glass fibers
  • Self-lubricating properties
  • Unique indexing function built into backing plate
  • Powerful geared grip with Tuff Lock™ Technology delivers an incredibly smooth, solid, vibration-free hold
  • Single-handed operation for fast, convenient mounting
  • Captured pinion and ball-nose Allen key with large, easy grip handle
  • Body made from precision machined 1045 high-tensile steel
  • Able to take all Nova accessory jaws (except Titan Power grip, which is specially designed for the Titan Chuck)
  • Four-jaw design firmly grips both round and square wood
  • Precision machined in one operation from a solid steel block for optimal accuracy
  • Polished metal finish to allow for closer tolerances and accuracy
  • Common accessory jaw fixing profile is compatible across all Nova chucks and accessories
  • Special woodturning dovetail profile on jaws
  • Auto safety stop feature so jaw slides can't protrude past the chuck body
  • Common insert/adaptor fitting is compatible across all Nova chucks (adaptor sold separately)
  • Safe Lock™ Woodworm screw included for fast mounting of rough timbers

Package includes a set of 12'' Cole Jaws for final finishing of bowl bottoms, plus the Cole Jaw Buffer Kit for a more secure grip on your turnings!

The Nova 12'' Cole Jaws are designed for re-chucking bowls with the bottom side exposed in order to remove chuck marks, add decoration or to re-shape the bottom of the bowl. They are suitable for lathes with a minimum 16'' swing diameter. Other Nova jaw sets can be fitted to the Cole Jaws for a variety of mounting options, and custom wooden jaws can also be created for unique situations. The included 6030 Jaw Buffer Kit extends the workholding potential of the Cole Jaws for turned edge bowls and large diameter cylinders. The kit includes two different sets of buffers—multi-sided buffers and long pin buffers—to cover most workholding requirements. The multi-sided buffers are reinforced with steel so they won't deform under pressure and pull the turning blank away from the jaws. The pin buffers are designed for maximum surface contact on longer turnings. Eight of each style are included, along with fastenings.


  • A fast, easy way of re-chucking bowls to make the finishing cuts on the bottom side
  • Holds a wide range of bowl sizes safely
  • Other jaws can be attached for more mounting versatility
  • Exceptional structural strength

Usage Tips: 

  • While traditionally these type of jaws are used in the compression mode, depending on the bowl shape, the jaws can be used to grip in either the contracting or expanding mode
  • To ensure best grip, the bowl should have a positive or negative flair towards the edge of the bowl
  • Try to avoid straight-sided bowls where the grip will be less efficient
  • Best practice is to have a cutting action such that much of the chisel force is directed towards the headstock, not across the face

Important Note: Only use authentic NOVA accessories on your NOVA chuck. Using non-genuine NOVA and copies of accessories could lead to operation and safety issues and will void the warranty. NOVA accessories are designed for use only on NOVA Chucks. Do not use on any other chuck.
