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
