The NOVA JSPIN Pin Accessory Jaw set has a long nose, designed to act as a pin chuck – expanding into a pre-bored hole, a very useful technique for free-form edged bowls. It is not necessary 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. Twist drills can be gripped to enable the chuck to be used as a drill chuck. The jaw-set features a small dovetail to mount small bowls.EXPANDING GRIP25.9mm (1.02") – 46mm (1.81")CONTRACTING GRIPSquare: 28mm (1.10") – 7mm (0.27")Spigot: 31mm (1.22") – 9.9mm (0.39")Actual sizes may vary depending on which NOVA chuck is being used.These special 25mm extended jaws are designed to act like a pin chuck - expanding into a pre-bored hole.
