Aluminum soft jaws are essential for any machine shop. They give shops the flexibility to utilize vices and not worry about damaging the parts being worked on. Unlike other vices, both sides of these jaws can be used to increase their longevity and allow machinists to do more instead of relying on only one side. They have an industry standard hole pattern that fits most manufacturers' vises, including Kurt, Chick, TE-CO, Toolex, and Palmgren. All parts are manufactured and use material sourced in the United States. 1 pair of jaws included in purchase.
