Do they have to be spot on 1" & 2"? Because if you know an industrial electrician, ask him if you can use his greenlee slug-buster, this is a panel punch for conduit holes in electrical panels, this makes a quick clean hole, although you can get 1" & 2" exactly, most electricians have the conduit sizes which are slightly under and slightly over those dimensions.
