Our company's Stainless Vise (shown as diagram): Jaw depth is 50 mm (1.96"). All workpieces with non-regular shapes can be fixed, and also can be moved forward and backward. Therefore, the processing will be easy. The bottom of our Vise's jaw is wide and the opening is narrow, which is totally different from the shape of common Stainless Vise as wide opening and narrow bottom. Our Vise is more stable than other common one during the processing. All common Stainless Vises are designed as wide opening and narrow bottom, and therefore all workpiece can't be fixed firmly.
