The Nova Titan provides a high-power geared chuck option, delivers aggressive holding power, and is ideal for larger lathes with a diameter swing up to 33". This solid 5"-diameter chuck has larger jaw capacity and is capable of handling much larger projects. With the optional Power Grip Jaws (128178), you can turn up to 33"-diameter bowls and spigots up to 19". The Titan can also take all of the accessory jaw sets in Nova Chuck accessory range; however, because of its larger size, we recommend appropriate larger accessory jaws as the perfect match. A fully sealed backing plate prevents buildup of wood dust, ensuring minimal maintenance, and the powerful geared grip with Tuff Lock™ Technology delivers smooth operation and superior holding power. The chuck key has fast, positive location that is both easy and comfortable to use, and the ball nose Allen key has a large, easy grip handle for fast, positive location.
