Item# NOVA 25mm (1″) Jaw Set (SKU JS25N)

Designed to expand your range and capacity of your standard NOVA chuck for specific projects and applications. Universally fits to any NOVA chuck for maximum flexibility, saving money as duplicate accessories are not needed for different NOVA chucks. This jaw set is for small bowls and unsupported small spigot turning and is ideal for midi/mini lathe work. Features a special NOVA wood turning dovetail profile, designed specifically for maximum strength and holding in wood turning without crushing the wood fibers. These jaws will hold in both the contraction and the expansion modes. Precisely machined from a single solid piece of 1045 high tensile steel for accurate closing, durability and long life. Comes with 4 jaw segments and instructions. Uses the standard fasteners that come with your NOVA Chuck. The 25mm jaw set substitutes for the standard 50mm jaws for use on small work with 3/8″-1-1/4″ spigots, as a type of pin chuck with 1″ capacity, for expanding dovetail work on bowls up to 6″ dia. and for 1/2″-1″ square blanks.



  • A quick and easy workholding solution for small bowls and small unsupported spigot work.
  • A great range of smaller projects can be mounted and turned using either the expansion mode (mostly for bowls) or the contraction mode (mostly for spigots)
  • Multiple turned pieces (i.e. lace bobbins) can be turned from dowel stock
  • Made from K1045 steel for maximum structural strength.
  • The standard Woodworm Screw (included with NOVA chucks) can be used with these jaws.
  • Only NOVA chucks give you the same jaw fixing system and same insert/adapter system across all standard chuck models, giving you optimal flexibility. All of the accessory jaws will fit all of the standard NOVA chucks. NOVA Infinity Quick Change requires optional accessory Upgrade Kit or Retro Fit Kit to attach standard NOVA Accessories. However, due to sizing, some jaws are not recommended for use on all NOVA chucks. See manual 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.
