Abstract

A hold down tool comprising an elongated body having a front surface engageable with a workpiece and a rear surface provided with embedded magnet means for retaining the hold down tool on the clamping face of a vise jaw. The rear face in which the magnet means is embedded is formed on a plane that is non-parallel with the front surface of the hold down tool so that the hold down tool provides a "pinching down" force on a workpiece engaged by the front surface of the hold down tool. The hold down tool is self-sustained.
