Product Description

The Austempered Ductile Iron (ADI) series of professional grade bench vises is constructed out of 130,000 PSI Tensile Strength Austempered Ductile Iron and is at least 45% stronger than the Yost FSV (forged steel) vise series. ADI castings are (1) continuous cast, precision machined, whereas the FSV series was forged then welded together. The ADI line of vises is equipped with replaceable machinist and pipe jaws. Adjustable hardened guide rails provide smooth, precise operation. The durable powder coat finish provides a professional finish that helps prevent damage from weather. The ADI base features two lockdowns for a tight grip.
