Premium Quality Structure: 45# steel jaws, after high-frequency quenching, undergo improving the wear resistance and service life of the jaws. Vise body for the QT500 ductile cast iron forging, which has good toughness, high strength, and durability. Powerful Clamping Force: Vise guide surfaces are finely polished, smooth surface. When clamping the workpiece, the movement is stable, the positioning is accurate, and the clamping force can reach up to 19 KN, which is suitable for workpieces of different sizes. High Accuracy Screw: The closed design protects the screw rod and prevents the entry of iron pins and other debris, which is convenient for maintenance and cleaning. The vise can be used not only horizontally, sideways, but also vertically, without affecting its precision. Humanized Design: Our vises are detachable and can be quickly changed. The unique downward pressure design prevents the workpiece from floating when clamped. The hardened swivel handle is a universal joint structure, easy operation, flexible, and convenient to use. Multifunctional Tool: Jaw Width: 4" (100 mm), Jaw Opening: 4.7" (120 mm). Milling Vise is an essential tool for fitters. Most work of the fitters is running by using the clamping vise such as sawing, filing, chiseling, and some assembly and removal jobs.
