Abstract: An installation tool is disclosed for installing an insert in a workpiece to the correct depth and swaging it in a single operation. The tool includes a mandrel having an externally threaded shaft at its outer end for engaging the insert. The mandrel is rotated to install the insert in the workpiece to the correct depth by a motor having an output shaft connected to the mandrel by a first clutch assembly. After the insert has been installed to the correct depth, the mandrel stops rotating and the first clutch assembly disengages. A second clutch assembly then engages with the output shaft causing a swaging element to advance outwardly from the tool to swage the insert in the workpiece. When the swaging operation has been completed, the motor reverses direction and withdraws from the workpiece.
