An air drill includes a body having a grip portion having an air supply passage and an air exhaust passage formed therein, a trigger portion formed above the grip portion and supporting a trigger, and a cylinder portion formed above the trigger portion and accommodating an air motor. A reverse valve is disposed within the cylinder portion in order to switch the direction of rotation of the air motor between forward and reverse directions. Two reverse levers are disposed in an upper portion of the reverse valve and slidably accommodated in two slit-shaped openings, respectively, which are formed in a grip-portion-side end of the cylinder portion.
