Abstract
A power tool is provided including a housing including a motor case and a handle; an electric motor housed within the motor case and rotatably driving a motor spindle; a gear case mounted on the housing; and an output spindle rotatably coupled to the motor spindle. The output spindle, motor spindle, and the handle form the plane through the housing. A fan is coupled to the motor to generate an airflow through the housing. The housing includes a first air inlet on a first side of the plane and a second air inlet a second side of the plane opposite the first air inlet, both adjacent the motor. The first air inlet is larger than the second air inlet to allow a larger volume of air to enter the housing from the first side of the plane than from the second side of the plane.
