The utility model relates to a special tool for constructing an industrial furnace, in particular to a novel air pick flat plate drill bit which is used for tamping a carbon thickener during the process of repairing a furnace edge at side part of a prebaked aluminium cell. The novel air pick flat plate drill bit comprises a air pick drill bit, a strengthening rib plate and a drill bit flat plate, after the head part with the length about 8 mm of a common drill bit is cut, a rectangle flat plate is welded at the end of the drill bit with the 90 degree angle, therefore, the air pick conical drill bit is changed into a flat plate drill bit. When the flat plate drill bit is used for tamping and pressing a carbon cold ramming thickener, the danger that the conical drill bit is jabbed into a work shoe to hurt workers is reduced, the working efficiency of repairing groove is increased, the labor intensity of workers is reduced; the compactness of the thickener is increased, the mechanical strength is increased after
