Step Drill
Although expensive, step drills can cut a variety of diameters and are great for thin materials like sheet metal. These drill bits have a stepped profile and increase in size the deeper the hole. The downside to step bits is that they do not work on materials thicker than 3/16 of an inch. Also, they might require a pilot hole before drilling.
Warning: When you use these drill bits on aluminum. The coating can easily end up welded to the metal.
