Abstract
A power tool is provided comprising: a motor, an output shaft driven by the motor along a longitudinal axis, a fan rotationally coupled to the motor to generate an airflow, and a housing comprising two calm shells mated together to support the motor and forming a back wall behind the motor along the longitudinal axis. The rear wall includes a plurality of air intakes. An end cap is attached to the housing adjacent the rear wall with an air gap therebetween. The airflow generated by the fan enters through the air gap in a substantially radial direction, then passes through the plurality of air intakes to enter the housing in thermal contact with the motor.
