Which means drilling a number of different hole sizes starts to add up - unlike a step bit that James mentions. This would certainly be more for a production enviroment.

I would use almost anything before I would try to cut a big hole in thin sheet metal with twist bit. Why didn’t they show a picture of a step bit or a punched hole?

Much better than hole saws which really aren't much good for deep holes. They get expensive as the size gets larger - and for a lot of stuff a unibit is just as good. People often use the rotaboraches in mag drills as well. There are also Val-Cut trepanning tools, which are pretty cool: (UK seller, not sure who handles them in the US, SPI maybe?) http://www.lineartools.co.uk/script/site/page.asp?artid=86&cat_id=70 (homepage in German) http://www.valcut.ch/valcut-werkzeuge.htm A machinist friend uses these all the time on his milling machine - they make nice round holes.
