A power tool includes a motor disposed in a motor housing, a handle extending downward from the motor housing, a main switch provided on the handle and configured to switch the motor ON and OFF, and a state-changing operation part located on a lower portion of the motor housing or on an upper-end portion of the handle. The state-changing operation part is located upward of the main switch and is configured to effect a change of a rotational state of the motor, other than a direction of rotation of the motor, or an illumination level of a light.
