How well do the el cheapo hammer drills with chisel bits do at cutting off
nuts and bolts? I've got some in very inaccessible places where I can't get
any tool but an air chisel of an electric hammer drill with chisel. Not
confident my air compressor will carry the air chisel. Bolts I need to cut
are 3/8".

They won't at all. Hammer drills have rotary and rotary/hammer modes,
they do not have a hammer only mode for use with chisels. A rotary
hammer will have a hammer only mode and cost a lot more. Try a good
chisel and a normal human powered hammer if your compressor isn't up to
powering an air chisel.

I would think that if you can get a hammer drill into this space you could
get a sawzall blade into there to cut your bolts off. You can buy them cheap
also.

Chisels are not the way to go. Use a pneumatic cutoff tool, a grinder
or a sawzall with a good blade. Watch for hot metal bits on you and on
anything that might catch fire. If it's wood framing wet down the area
with a spray bottle.

a dremel tool with cut off wheels cuts through even hardened steel nuts and
bolts, though can be a very dangerous tool capable of causing bodily injury
or even death
