An improved air tool includes an integrated air motor and electrical generator wherein the stator is positioned on a side of the rotor body opposite the working end of the tool to reduce vibrations transmitted to the stator. The stator is also positioned between the compressed air inlet and the rotor body such that compressed air flows across the stator to prevent overheating of the stator. The air tool includes an indicating circuit connected to the battery charging circuit for indicating a battery charge condition, a battery discharge condition, and a low lubrication condition of the air vanes. A light ring assembly is attached to the working end of the tool housing to provide light at the working end of the tool. Materials chosen for the magnets and the poles of the stator increase the power capability of the electrical generator. An illuminating apparatus for a conventional air tool includes a light ring with integral generator.
