A power tool comprises: a housing; an output member at least partially contained in the housing and configured to rotate about a longitudinal axis; a motor contained in the housing and drivably connected to the output member to impart rotary motion thereto; and a rotational motion sensor arranged in the housing and operable to detect rotational motion of the housing, from a first reference orientation of the housing, about the longitudinal axis of the output member. A controller is also located in the housing, the controller configured to receive a signal indicative of the rotational motion from the rotational motion sensor and, in response to the signal, to drive the motor to rotate the output member. The power tool also includes a reset switch configured to reset the rotational motion sensor to a second reference orientation of the housing, which is different to the first reference orientation, upon actuation of the reset switch, the second reference orientation then being the reference orientation from which the rotational motion sensor is operable to detect the rotational motion of the housing.
