Abstract
An electric power tool in one aspect of the present disclosure comprises a motor, a hitting mechanism, a hitting detector, and a control unit. The control unit is configured to set a control amount of the motor so that the motor rotates at a lower speed than a speed in the target rotation state during an initial driving period, and switch the control amount to a final control amount corresponding to the target rotation state when the initial driving period elapses. The initial driving period is a period from when generation of a hitting force is detected by the hitting detector until a predetermined first time period elapses, after the motor is started driven.
