While you guy are checking the Electrician's nuts and tightening your nipples, Greenlee makes a step drill bit that I believe will cut to 1 1/2" holes. Both Lowes and HD have them ( @ $50+ ) along with a 7/8" bit ( $35 ) They are kind of hidden near the wiring and conduits.
I'd like to see the progress!
