Help drilling hole through concrete slab?
 
I want to put in a sand point well in my garage and run a garden hose spigot through the wall. I am under the impression that I can drill a hole through the slab with a 2 inch masonry hole saw. I see a problem with hitting rebar or wire mesh. What's the solution in that case? Also has anyone ever put in a sandpoint? Anything you would have done differently? Thanks for the help.

2 inch hole saws are usually sintered diamond hole saws used with water from what I remember? if so that diamond bit will go right through rebar as long as it has water to cool/lubricate

Yep, just keep it wet and relatively slow and it will chew through almost anything.

For a garden hose faucet you could probably run a half inch pipe, so you could just use a 3/4 inch bit on your hammerdrill...

I'd just rent (or borrow) a rotary hammer. Lots faster than a hole saw. No need for lube, and chews right through concrete. BTW, use hydraulic cement to seal back up around the pipe when you're all done.

Maybe use your pinpointer to locate rebar.
