Abstract: A drilling-out aid device for assisting in drilling out a rivet, in particular a blind rivet, by a drilling tool, includes a proximal handle portion for handling the drilling-out aid device; a guide device for centrically guiding a drilling shaft of the drilling tool; a distal rivet-head receiving device for centrically orientating the drilling-out aid device on the head of the rivet to be drilled out; and a rivet-head pressing device, which is mounted displaceably in the longitudinal direction of the drilling-out aid device relative to the rivet-head receiving device to apply a centric gripping force to the head of the rivet to be drilled out.

Abstract: A fastening device includes a fastening needle system, which is guided in a base body of the fastening device. The fastening needle system is configured to be led through a drilling hole of one or more components. By exercising a pulling force onto the fastening needle system, the components can be fastened between the front portion of the fastening needle and the base body. A fastening system may include the fastening device and a fastening pliers.
