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.

Abstract: A power tool includes a soft-stop transmission having a first component and a second component. The first component is configured to receive torque from a motor to rotate the first component in a first rotational direction. The second component is connected to an output of the power tool and is configured to rotate in a first rotational direction in unison with the first component. The second component is configured to rotate in the first rotational direction relative to the first component in response to angular deceleration of the first component. A damping element is positioned between the first component and second component, and the damping element is configured to bias the first component in the first rotational direction and the second component in an opposite, second rotational direction.
