Nova jaw sets add even greater versatility to the Nova Midi, SuperNova2 and Nova Titan chucks. Each set is precision machined from a high quality solid steel billet and comes with an easy to read instruction manual. Long Nose Jaw Set features an internal dovetail and threaded serrations. This new jaw has a superior grip in the spigot mode - ideal for holding larger and longer tenons. The extra long nose is invaluable when working near the bottom of a bowl, allowing extra distance between chuck and workpiece. Fits all Nova Chucks.
