These jaws are perfect for drilling pen blanks. They eliminate the need for a drill press and offer much more accurate results because the deep grip to all four sides ensures excellent holding power. Drilling on the lathe means the feed speed of the drill bit is under complete control so that 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.
