Abstract
An electric tool includes an output shaft and a controller. The output shaft is configured to hold a tip tool and be rotated by motive power provided from an electric motor with the output shaft holding the tip tool. The controller is configured to control rotation of the output shaft in accordance with pressing force in a direction from a tip end of the tip tool toward the output shaft. The electric tool has, as an operation range, a restriction range in which rotation of the output shaft is restricted in a state where the pressing force is less than or equal to a prescribed value.
