PROBLEM TO BE SOLVED: To provide an electric power tool capable of achieving not only downsizing and cost reduction but also high performance.SOLUTION: An electric power tool comprises multiple kinds of transfer mechanisms to transfer a rotary driving force from a motor 30 to a tool output shaft. In addition, the electric power tool also has multiple operation modes. When one of the operation modes is set, the transfer mechanism is switched to the kind of the transfer mechanism suitable to the set operation mode so that the motor 30 will be controlled by the control method suitable to the set operation mode. |
