An ordinary electric drill with a hammer option will do the job using
tungsten carbide bits. You will need an inverter if you want to run the
drill off a car battery. Are you collecting samples for analysis?

How about a hammer drill ?

May not do smooth work but it'll sure place a hole
in that rock! :)

The OP should look into the drills that cavers use when
placing climbing bolts. Cavers have *serious* constraints
on battery weight/life, since the drill may need to be lugged
for many hours through rugged passages to get to where it
is needed.
