Abstract

A power tool includes a housing, a motor supported within the housing, a handle extending from the housing, a trigger, a spindle, and a fluid delivery system. The handle defines a gap between the handle and the housing, and the trigger, coupled to the housing, is manipulable to energize the motor. The spindle is configured to rotate about a rotation axis in response to torque received from the motor, and the fluid delivery system is configured to supply fluid to the spindle. The fluid delivery system includes a valve operable to regulate a flow of fluid to the spindle, and the valve includes an actuator disposed within the gap.
