This heavy duty bench vise is designed to be used by the home craftsman to the professional woodworker. The rugged high-strength steel and iron constuction makes it strong and durable. A formed steel channel covers the cold rolled acme screw, protecting it from debris. This vise is equipped with a 120 degree swivel base and double lock downs for secure mounting. Replaceable jaws have serrated faces, providing positive grip. Built-in anvil provides an additional working/striking surface.
