Three-jaw chucks are designed so that all three jaws move together and automatically center round or hexagonal parts or stock to within a few thousandths of an inch. These chucks provide the quickest and easiest way of holding work in the lathe. For this reason, they are the most popular of the Sherline accessories. The Sherline 3-jaw chucks are designed so that they can be used to clamp externally on bar stock or internally on tube stock. The jaws are reversible to accommodate larger stock.
