Abstract
A power tool includes a housing with a motor housing portion and a drive housing portion, a handle extending from the housing and defining a gap between the handle and the housing, a motor located within the motor housing portion having a motor output shaft, a fan coupled to the motor output shaft, a battery to provide power to the motor, a trigger coupled to the handle and manipulable to energize the motor, a spindle extending within the drive housing portion and driven by the motor output shaft to rotate about an axis, and a fluid delivery system configured to supply a fluid to the spindle. The housing includes an air intake opening and a deflector to inhibit the fluid from entering the housing through the air intake opening, and rotation of the fan draws an airflow into the housing through the air intake opening.
