Abstract

The invention relates to a system for securing an anchor in a borehole in a mineral substrate, in particular concrete, mortar, or brickwork, comprising an anchor with a core section and a threaded section and comprising a furrowing tool for furrowing an internal thread in the borehole, said furrowing tool comprising the following: a main part with a leading end and a trailing end, wherein a force is applied via which a torque can be transmitted to the main part in order to rotate the furrowing tool (10) into the borehole and furrow the thread, and the main part has an outer surface equipped with a furrowing thread which is suitable for furrowing the internal thread into the wall of the borehole. The furrowing tool has a drive element on the leading end of the furrowing tool, said drive element being suitable for interacting with an application of force to the anchor or a part thereof which is to be screwed into the borehole machined by the furrowing tool.
