The utility model relates to a marking tool used for machining a planar workpiece. The marking tool is characterized by comprising an ejection rod support. An ejection rod and a spring connected with the ejection rod are arranged in an inner cavity of the ejection rod support, the upper end of the ejection rod is connected with a marking tip, the wall of the ejection rod support is provided with a radial limiting groove, and a guide mechanism used for guiding movement of the tip is installed in the radial limiting groove of the ejection rod support. The marking tool has the advantages that the marking tool is clamped to a chuck of a machine tool spindle, the program of a numerical control machine tool is set according to the needed marking track, and then all the faces of the workpiece are marked through the marking tool according to the set program of the numerical control machine tool. Compared with the prior art, the marking tool solves the problem that due to the difference of marking technique levels of workers, the marking precision is influenced, and can greatly improve the quality of the workpiece and the machining efficiency.
