The NOVA 6114 3" Pro-Tek Jaws are a scaled-up version of the Hornung design borrowing the proven double-dovetail and serrated construction that earned acclaim on the 1″ model but reimagined for larger turning tasks. With added cut gaps for additional square stock holding and aimed at mid-size workpieces where stability and grip are essential, it maintains the balance of precision and torque that users trust. The NOVA PRO-TEK 3" Jaws Set has a true dovetail profile, designed for maximum strength and holding in wood turning, without crushing wood fibers. Engineered for strength and precision, the 3" PRO-TEK Jaws feature a full. 3-inch (76.2mm) diameter with a thick, true dovetail profile, designed to hold large projects with rock solid stability. Internal serrations provide maximum grip on spigots, while additional cut slots ensure square stock stays firmly in place. Perfectly sized for medium projects, this jaw delivers unbeatable control and confidence every time!
