Thanks guys.
Ed: Yes, they work great for sheet metal. In wood, if you are going all the way through, you should stop short and finish from the opposite side to get a clean hole all the way through.
OG: Punches are quicker, but more costly. These work just as well in a pinch. Sorry but sharpening end mills require a tool grinder, sharpening them by hand is not practical. It might be possible to sharpen the ends (I've never tried it), but the flutes require a tool grinder.
Greg, I've never been a fan of step drills. They work well, but seem to require a lot more effort than should be needed to drill a simple hole.
