In addition to step drills, annular cutters like Hougen RotaCut and Blair Rotabroach cutters work very well for cutting nice clean round holes in thinish aluminum. We have drilled literally thousands of lightening holes in aluminum angle & tube before using them. These are not the same as your everyday hole saw.
