The Proxxon MS 4 machine vise is a small and compact holder for workpieces on machine tables. Its compact design makes it particularly suitable for small to very small workpieces. The surfaces made of zinc die-cast are precisely machined, ensuring excellent support for the workpiece and optimal precision. A groove on the underside of the vise allows for easy and quick fixation on the TBM220 bench drill and the MB 140/S drill stand. To securely clamp round materials such as small pipes or round bars, a V-groove is machined into the clamping jaw to prevent slipping. The clamping force of the machine vise can be adjusted very precisely using the yellow knob.
