If a bit is not making chips, it's just making heat. Was the drill variable speed or gear reduced? 6" hole saw should not spin fast. I still have an old corded Milwaukee angle drill for stuff like that, but I'd probably use a sawzall with a metal blade (so as not to chip the wood siding) and once the drywall was cut to make sure there are no wires or pipes, I'd probably work from the outside.
