Sam, unless you plan on drilling a lot of cast iron or stainless steels, uncoated high speed steel is fine and actually preferred for aluminum and plastics. Get your drills at an industrial supply house like Travers Tool, MSC, or McMaster Carr. You can choose import or domestic as well as manufacturer. Avoid places like Harbor Freight or Grizzly which are pretty much cheap imported stuff of dubious quality.
