A power tool for installing self-drilling mandrel-rivet assemblies comprises a rotary rivet-abutting nosepiece, a relatively retractable mandrel-pulling means rotatable with the nosepiece, and mechanism whereby the nosepiece and mandrel-pulling means are rotated to enable a rivet assembly to drill a hole in a workpiece for receiving the rivet and thereafter relatively retract the mandrel-pulling means to set the rivet in the hole. |
