Product Description

31mm Mini Jaws

Mini Spigot Accessory Jaw Set is an accessory for NOVA chucks, designed to expand your range and capacity of your standard NOVA chuck for specific projects and applications. 

  • Longer jaws allow for a very powerful spigot grip for smaller work such as lace bobbins.
  • These special 25mm extended jaws are designed to act as a pin chuck, expanding into a pre-bored hole. This is an especially useful holding method for bowls with a free-form edge.
  • A big advantage over pin chucks is that you don’t have to bore to an exact size – any size between the minimum and just under the maximum expansion will do.
  • The longer jaw length allows for a very powerful spigot grip for smaller work like lace bobbins (up to 6″ in length) and delicate pots.

Expanding Grip 24.9mm (.98”) – 45mm (1.77”)
Contracting Grip Square: 31mm (1.22”) – 9.9mm (.39”) Spigot: 30mm (1.18”) – 7.9mm (.31”)
