Jesus, I hope you guys are merely ignorant.

You need to use a sheet metal hole cutter, not a hole saw. These are way different and don't tear up the edges or cause terrible accident. With metal plate you use a hole saw, but not sheet metal, it is too thin.

You need to use one of these for sheet metal holes.

Just attach the device to a drill or whatever you have to run them with.
