An installation tool (10) is disclosed for installing an insert (12) in a workpiece (14) to the correct depth and swaging it in a single operation. The tool (10) includes a mandrel (34) having an externally threaded shaft (36) at its outer end for engaging the insert (12). The mandrel (34) is rotated to install the insert (12) in the workpiece (14) to the correct depth by a motor having an output shaft (42) connected to the mandrel (34) by a first clutch assembly (44). After the insert (12) has been installed to the correct depth, the mandrel (34) stops rotating and the first clutch assembly (44) disengages. A second clutch assembly (74) then engages with the output shaft (42) causing a swaging element (102) to advance outwardly from the tool (10) to swage the insert (12) in the workpiece (14). When the swaging operation has been completed, the motor reverses direction and withdraws from the workpiece (10). <IMAGE> |
