These deep, heavy-duty jaws feature a robust cross section for strength, dovetail interior and exterior taper on the end of the jaw for traditional chucking and a series of serrations on the interior to provide a tenacious grip on a spigot. The large face of the jaw provides excellent registration for the work piece making it ideal for large bowls and platters.
