Item #
82% of 100
The Nova Standard 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 12"/300mm swing diameter. Other Nova jaw sets (sold separately) 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 optional 6030 Jaw Buffer Kit (#43974, sold separately) also greatly extends the workholding potential of the Cole Jaws. See the Mini Cole Jaws (#45274, sold separately) for lathes with a minimum 8Designed for lathes with a minimum 12"/300mm swing diameter.


  • Designed for lathes with a minimum 12"/300mm swing diameter.
  • Max workpiece diameter with Precision Midi chuck: 8.661" (external grip); 11" (internal grip).
  • Max workpiece diameter with Nova G3 chuck: 9.291" (external grip); 11" (internal grip).
  • Max workpiece diameter with Supernova 2 chuck: 9.291" (external grip); 11" (internal grip).
  • Max workpiece diameter with Titan chuck: 9.449" (external grip); 11" (internal grip).
  • For replacement bumpers, see the Nova Cole Jaw Fastening Kit (#44091, sold separately).
  • A fast, easy way of re-chucking bowls to make the finishing cuts on the bottom side.
  • Fits all Teknatool chucks.
  • Holds a wide range of bowl sizes safely.
  • Other jaws can be attached for more mounting versatility.
  • Exceptional structural strength.
  • Nova chucks give you the same jaw fixing system and same insert/adapter system across all chuck models.
  • All accessory jaws in the range will fit all the chucks in the range for optimum flexibility. Some, however, are not recommended. See individual jaws for recommendations.
  • Nova chucks are specially designed so the jaws cut into the wood, grip firmly in the contraction mode and provide high tear out 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.

Nova Cole Jaw Set
Love these jaws they make finishing the bottoms of bowls so easy. I had to read the directions twice to make sure I had it attached correctly. I had been a bit concerned because a few people had issues. I can see where you could have problems if you did not read the directions carefully.

great tool
easy to use, held my bowl firmly. Much easier than some of the online solutions where you turn a scrap piece of wood to hold the bowl, or pay a lot for a vacuum system. This tool is a must have for bowl turners.

I put the Cole chuck on G3 nova chuck and it is loose, should this be put under a set of 50 mm jaws as in the picture in the brochure supplied?
J A P on Jan 5, 2017
BEST ANSWER: These jaws replace whatever jaws you have on the chuck. It's a little tricky to align them correctly. Just like the smaller jaws, there are tabs on the back of the jaws that fit into slots on the chuck. Make sure there is no space between them, then tighten the mounting screws. Takes some fiddling, but perseverance pays.
