The utility model relates to a grounding conduction special-purpose tool, and belongs to the field of measurement of an electric power equipment grounding conduction tool. The grounding conduction special-purpose tool comprises a tool body (6). The tool body employs channel steel, a first hole (5) is arranged in the middle of the upper portion plane (7) of the tool body (6), the first hole (5) is internally provided with a screw rod (2), the screw rod (2) is provided with an external thread, the external thread is adaptive to the inner thread arranged in the first hole (5), the top of the screw rod (2) is provided with a second hole (3), the second hole (3) is internally provided with a torsion bar (4), and the bottom of the screw rod (2) is provided with a file surface (8). According to the utility model, an equipment grounding end is clamped through the tool body, the screw rod is rotated to move downwards by use of the torsion bar to enable the file surface at the bottom of the screw rod to be contacted with an equipment surface, and an anticorrosive coating or a corrosion layer of the equipment surface is polished by use of an uneven tip end at the bottom of the file surface, such that the use is convenient, the preparation time of a test is shortened, the test accuracy is ensured, and the practicality is quite high.
