ABSTRACT:
A workpiece support for a vise which is used for clamping a small workpiece on the vise and which can solve the problem that the prior art workpiece support has not versatility in clamping workpieces of various different configurations. In the workpiece support, a magnet is detachably mounted in a support plate and the support plate is fixedly attracted to a jaw plate of the vise through the magnet. Therefore, by forming a step in one side of the support plate along an edge and mounting the magnet in the support plate in a reversible manner, any one surface of the workpiece support can be selected as an attraction surface and the workpiece support can be used in many various forms depending on the workpiece configurations.
