Abstract
A fastening tool configured to fasten a workpiece via a multi-piece swage type fastener including a pin and a collar includes an anvil, a pin-gripping part, a driving mechanism, an electric motor, a control part and a housing. The driving mechanism is configured to move the pin-gripping part relative to the anvil in a first direction along an axis so as to cause the anvil to press the collar engaged with a shaft part of the pin in a second direction and in a radially inward direction. An operation mode of the driving mechanism can be selectively switched between a plurality of operation modes including a first mode, in which a process of fastening the workpiece is completed based on a state of the fastener, and a second mode, in which the process of fastening the workpiece is completed based on a driving state of the motor.
