Abstract
An electric power tool includes a motor, an output shaft, a drive force transmission configured to reduce drive speed of the motor and transmit drive force of the motor to the output shaft; a trigger that can be pulled by a user; a rotation speed changing circuitry configured to change a rotation speed of the output shaft that corresponds to a maximum pulled amount of the trigger to a limited rotation speed that is lower than a maximum rotation speed of the output shaft in a non-limited rotation speed mode; and a rotation speed control circuitry configured to control a rotation speed of the motor in correspondence with a pulled amount of the trigger to obtain the rotation speed of the output shaft that is changed by the rotation speed changing circuitry.
