Abstract: A screw driving includes a housing, a motor, a spindle, a locator, a first detecting mechanism and a controller. The locator is mounted on a front end portion of the housing so as to be movable in a front-rear direction relative to the housing and configured to define a depth to which a screw is driven into a workpiece. The first detecting mechanism is configured to detect a position of the locator in the front-rear direction. The controller is configured to control driving of the motor. Rotational driving of the spindle in a forward direction is started in response to the spindle being pressed rearward, and the rotational driving of the spindle in the forward direction is stopped when the first detecting mechanism detects that the locator is disposed in a specified position rearward of a most forward position within a moving range of the locator.
