The rigid and robust body, as well as the sliding jaw, are made of fine-grained gray cast iron, which has been processed for smooth and reliable operation on all friction surfaces. The jaws, the rod, and the threaded spindle are made of steel. The double-thread trapezoidal spindle allows for quick opening and closing of the jaws with a minimal number of turns. This compact bench vise with an anvil has been specifically designed for workshop applications with medium demands, catering to both professional craftsmen and discerning DIY enthusiasts who expect a compact vise with high clamping force, safety features, and excellent workmanship.
