I would like to drill a hole through my 8" concrete block wall to pass a
1/2" schedule 40 PVC pipe through from the outdoor to the inside courtyard
area to continue the sprinkler branch.

Problem is I have a 9/16" hammer drill, I don't have a mean heavy duty
demolition hammer drill.

I believe a 1/2" niminal PVC pipe has an outside diameter a little bigger
than 3/4". *Is there a masonry bit longer than 8" and wider than 3/4" that
could be used for my hammer drill? *Or do I need to rent a big one from the
tool store just for one hole?

If there is not one big enough, is there something else I can do to get
around this - for example, using 1/2" CPVC - those are much skinnier and if
I can just use that for the stretch through the block...don't know, probably
not a good idea.

Thanks,

Rent a rotary hammer. The drill bit that you will get with it will be
long enough. Cost isn't that high and there are times when trying to
do it "on the cheap" just isn't worth it.
