I know there was discussion about this awhile back, but I thought I'd again put in my 2 cents.
Yesterday I had to make a 4" hole thru my 8" basement block, that was filled with concrete.
This was done for my exhaust fan.
I rented a Milwaukee hammer drill, 5/8" bit on a 12" shaft, and the hammer chisel all for $35.00 for the day....no hourly rate.
I proceeded by drilling about 10 pilot holes around the exterior of my sketched outline
Then taking the power chisel I just chiseled out the interior.
Luckily, I missed the rebar!
It took about 45 min.
With clean up, a little over an hour.
Hope this helps someone.
I know there was talk about using water to cool things down,, not using a hammer drill because of damage to the exterior of the block.
All I can say is, I've done this before and this way works slick as snot!
If I would have been thinking I would have taken pics, but the duct is already in place....sorry.
