Universally fits to any NOVA Chuck* for maximum flexiblity, saving money as duplicate accessories are not needed for different NOVA Chucks. The NOVA JSPIN Pin Accessory Chuck Jaw set have a long nose, designed to act like a pin chuck - expanding into a pre-bored hole, a very useful technique for free form edged bowls. You don't have to bore an exact size as with other pin jaws. The longer jaws allow for a very powerful spigot grip for smaller work such as lace bobbins. They are also ideal for longer dowel work and pen blanks. Twist drils can also be gripped to enable the chuck to be used as a drill chuck. The jaw set features a small dovetail to mount small bowls. With a special NOVA wood turning dovetail profile, designed specifically for maximum strength and holding in wood turning, without crushing the wood fibres. 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 precise closing, durability and long life. Comes with 4 jaw segments and instructions. Uses the standard fasteners that come with your NOVA Chuck. Designed by the innovators of the 4 Jaw Chuck for wood turning, Teknatool International - since 1955. *Some accessories such as larger jaws are only suitable for use on the larger NOVA Chucks, please check manual prior to use.
