Setting tool and method for percussively driving an anchor rod into a borehole

A setting tool for percussively driving an expansion anchor into a borehole in a substrate, the setting tool having a drive-side end and, in a tool direction, an opposite end facing away from the drive-side end for receiving the expansion anchor, the setting tool comprising:

• a tool adapter adapted to interact with a driven impact tool at the drive-side end;
• a receiving element having a recess arranged at the opposite end to receive part of an anchor rod of the expansion anchor extending in a guide direction away from the setting tool;
• wherein the tool adapter and the receiving element are coupled to one another such that an impact force introduced at the drive-side end oriented in the tool direction toward the opposite end is transmitted to the anchor rod when received in the recess of the receiving element and oriented in the guide direction;
• and
• wherein the tool adapter and the receiving element are configured with an axial overlap region in the tool direction and are coupled by a coupling element including a coil spring such that, during a percussive driving in of the expansion anchor into a borehole, the coupling element allows pivoting movement in the axial overlap region and a displacement of at least part of the receiving element transversely to the tool direction.
