A hand held cleaning tool is powered by commonly available batteries. Preferably a momentary switch selectively delivers power from the batteries to a motor. An output shaft of the tool includes an expandable coupling, such as, for example a set of swaging cams. Torque delivery arms radiate outward from the output shaft. For example, the torque delivery arms are carried by a hub. The hub is attached to the output shaft with a pin. The hub also acts to secure a power train including the motor and output shaft to a housing of the cleaning tool. The torque delivery arms are received in slots or interdental spaces associated with a cleaning head. Torque is delivered to the cleaning head with a reduced stress concentration.
