The installation tool for a wire thread insert includes: a drive unit which provides a switchable rotation movement between a first and a second direction, a mandrel body with a drive section for rotating the mandrel body and with a drive section for rotating the mandrel body and with a thread section onto which the wire thread insert can be screwed or rotated on, an installation blade as well as a torque clutch consisting of a form-fit and force-fit clutch upper and lower parts engaging each other, of which the upper part is connected with the drive unit in a torque-proof manner and the lower part is connected with the mandrel body in a torque-proof manner. With a decoupled relative rotation between the clutch parts, caused by exceeding a limit torque between the clutch parts, relative movement between the mandrel body and the installation blade can be generated.
