These jaws are perfect for drilling pen blanks, eliminating the need for a drill press and offering 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 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 to allow greater access.
