How do I make square holes for bolts in metal control panel?

OK OK I take back my first answer......

The best way to cut these holes is with a "thermal lance" This is a high pressure gas plasma cutter cooled by liquid nitrogen on the end of a 12 foot pole designed for cutting through up to 4" plate steel.... Favoured by large scale safe crackers.  Works like a dream. Even cuts great trackball holes. ;)

Anyway!!! Who says the hole wants to be square... It's Like So Uncool to be square Dady'o...
