Rotary power tool

A power tool, comprising:

• a housing including a plurality of air intake openings, each having a first deflector, and a plurality of air exhaust openings, each having a second deflector;
• a motor located within the housing;
• a handle extending from the housing and defining a gap between the handle and the housing;
• a fan driven by the motor to generate an airflow from the plurality of air intake openings to the plurality of air exhaust openings to cool the motor;
• and
• a spindle driven by the motor to rotate about an axis.

A power tool, comprising:

• a housing including a motor housing portion and drive housing;
• a handle extending from the housing and defining a gap between the handle and the housing;
• a motor located within the motor housing portion;
• a drive assembly located within the drive housing, the drive assembly including a multi-speed transmission;
• a battery receptacle located below the motor housing portion and in front of the gap;
• a battery removably coupled to the battery receptacle and configured to provide power to the motor;
• a fan driven by the motor;
• a spindle extending from the drive housing and including a bit holder configured to receive a tool bit, the spindle being driven by the motor and the drive assembly to rotate about an axis;
• and
• a printed circuit board (PCB) located between the handle and the motor,
• wherein the housing includes an air intake opening and an air exhaust opening,
• wherein rotation of the fan draws an airflow into the housing through the air intake opening and discharges at least a portion of the airflow through the air exhaust opening, and
• wherein the airflow flows past the PCB to cool the PCB and then flows past the motor to cool the motor.
