To enable the use of the full load-bearing capacity of the rebar connection, the professional and approval-compliant creation of the drill hole must be ensured. The fischer drilling aid is a guide device for the creation of drill holes for rebar connections. It simplifies the creation of drill holes for rebar connections and enables precise drilling next to the component edge or parallel to an existing reinforcement. The drilling aid is secured with a plug to achieve this. The pivotable guide rod acts as an optical guide for parallel drilling.
