These jaws are fantastically effective for drilling pen blanks. They eliminate the need for a drill press and offer much more accurate results and the deep grip to all four sides ensures incredible holding power.
Drilling on the lathe means the feed speed of the drill bit is under your complete control, meaning a superior finish can be achieved on a wide range of materials.
These jaws are also useful for working on small finials and similar projects as in addition to their strong grip, the work piece is moved forward from the chuck, allowing greater access.
This jaw set is completely cross compatible with all previous Nova chucks and the Robert Sorby Patriot chuck.
