3.1″ 3-Jaw Self-Centering Chuck Body – ER-16 Thread
Three-jaw self centering 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. They 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.
