Summary:The invention relates to the technical field of engineering machinery drilling tools, in particular to a drilling tool body. The drilling tool body is provided with two discarded drilling tools. The drilling tool body is characterized in that one ends of the two discarded drilling tools are cut into inclined sections separately; one sides of the center lines of the inclined sections are cut into semi-arc planes of which the sections are in fan shapes; one of the discarded drilling tools and the other discarded drilling tool are connected in a butt joint mode through the center lines; the inclined section of the one discarded drilling tool corresponds to the semi-arc plane of the other discarded drilling tool; the inclined sections and the semi-arc planes of the two discarded drilling tools form a cavity; and the cavity is filled with metal welding materials so as to enable the two discarded drilling tools to form the coaxial drilling tool body. The function of waste reuse is achieved, materials are saved, and
