A tool ( 1 ) is constructed for single use for making drill-holes in bones or removing cylindrical drill-hole cores from bones of the human body with a tubular tool body ( 2 ) which can be inserted into a receiving bore ( 8 ) of a tool holder ( 4 ). At least one cutout ( 5 ) in the tool body ( 2 ) and at least one protrusion ( 10 ) of the tool holder are coupled to rotationally affix the tool ( 1 ) to the tool holder ( 4 ). In the process, a flexible tongue ( 15 ) on the tool body ( 2 ) latches into an opening ( 16 ) of the tool holder ( 4 ) to axially fix the tool body. After the tool ( 1 ) has been used, the tongue ( 15 ) can be pushed out of the opening from outside, with plastic deformation, so that the tool can no longer be connected to the tool holder ( 4 ).
