Abstract
A setting tool used in a method for percussively driving an anchor rod into a borehole in a substrate has a drive-side end and, in an opposite tool direction, an end facing away from the drive. The setting tool has a tool adapter that forms the drive-side end and is arranged to interact with a driven impact tool. The end facing away from the drive is formed by a receiving element that has a recess arranged to receive part of an anchor rod. The tool adapter and the receiving element are coupled together by a coupling element such that an impact force introduced via the tool adapter is transmitted to an anchor rod arranged in the recess of the receiving element. The coupling element, in particular a coil spring, is arranged to allow for a displacement of at least part of the receiving element transversely to the tool direction.
