For drilling holes (not cores) in hard substrata, rotary hammer drills 
are much faster than plain rotary drills. There are pneumatic versions. 
Google for more info.

I know that you can use a pneumatic drill hooked up to a scuba tank. I was wondering if anyone had details on a setup they use and any modifications that are needed to the drill.
