The Vevor 4" milling vise is a precision fixed bench clamp designed for milling, drilling, filing, chiseling, and general workshop holding tasks. Its body is made from QT500 ductile cast iron with hardened 45# steel jaws for strength, wear resistance, and long service life. The vise delivers up to 19 kN of clamping force for secure and accurate workpiece positioning. A closed screw design helps protect internal components from debris and supports easier maintenance. Its downward pressure design helps reduce workpiece lift during clamping.
