What's the best way to punch a 2" hole for a drain pipe through a
cinder
block wall?

I've researched a variety of suggestions from a hammer and a star
drill, to
drilling a ring of small holes in a circle with a carbide bit to
renting or
buying a diamond tipped core bit. What's the best way of doing it so
as
NOT to crack the block?


How about a carbide hole saw?

If you don't mind the noise, a ,22 rifle can get the job done. Watch
out for block & bullets bouncing

I'll keep that in mind.
