A drilling tool having an exchangeable insert, the drilling tool comprising a shank, a clamping end, a drill head and a longitudinal axis, wherein a receptacle for the exchangeable insert is formed on the drill head, wherein the receptacle comprises two drivers (15, 17), wherein a support surface is formed on each driver (15, 17), wherein the normal vectors of the support surfaces are orthogonal to the longitudinal axis, wherein the drivers (15, 17) are arranged centrally symmetrically with respect to the longitudinal axis, wherein a centering surface is formed adjacent to the support surface of a driver (15, 17), wherein a centering surface is formed adjacent to the support surface of a driver (15, 17), wherein the centering surface forms an angle (alpha) of between 120° and 60° with the support surface, wherein a fitting surface is formed adjacent to the centering surface, wherein a base surface is formed between the drivers (15, 17) at the transition between the drill head and the drivers (15, 17), and wherein the base surface is rotationally symmetrical with respect to the longitudinal axis, wherein the drill head has securing means for securing the exchangeable insert against falling out, wherein the exchangeable insert comprises a front portion, a prismatic fastening portion and a longitudinal axis, wherein the front portion has one or more cutting edges, and wherein the fastening portion is designed such that it cooperates in a form-fitting manner with the drivers (15, 17) of the drilling tool, characterized in that the securing means comprise a transverse bore formed as a stepped bore in the drill head, in that the transverse bore passes through both drivers (15, 17), in that the transverse bore has an internal thread in a driver, and in that at one end of the fastening portion a recess is formed which is aligned with the transverse bore of the drilling tool. wherein a receptacle for the exchangeable insert is formed on the drill head, wherein the receptacle comprises two drivers (15, 17), wherein a support surface is formed on each driver (15, 17), wherein the normal vectors of the support surfaces are orthogonal to the longitudinal axis, wherein the drivers (15, 17) are arranged centrally symmetrically with respect to the longitudinal axis, wherein a centering surface is formed adjacent to the support surface of a driver (15, 17), wherein a centering surface is formed adjacent to the support surface of a driver (15, 17), wherein the centering surface forms an angle (alpha) of between 120° and 60° with the support surface, wherein a fitting surface is formed adjacent to the centering surface, wherein a base surface is formed between the drivers (15, 17) at the transition between the drill head and the drivers (15, 17), and wherein the base surface is rotationally symmetrical with respect to the longitudinal axis, wherein the drill head has securing means for securing the exchangeable insert against falling out, wherein the exchangeable insert comprises a front portion, a prismatic fastening portion and a longitudinal axis, wherein the front portion has one or more cutting edges, and wherein the fastening portion is designed such that it cooperates in a form-fitting manner with the drivers (15, 17) of the drilling tool, characterized in that the securing means comprise a transverse bore formed as a stepped bore in the drill head, in that the transverse bore passes through both drivers (15, 17), in that the transverse bore has an internal thread in a driver, and in that at one end of the fastening portion a recess is formed which is aligned with the transverse bore of the drilling tool.
