Thanks for the advice. I did not know how the chisel bits were used and know
I understand. Thanks again!

if they could make a hole that is anywhere close to round. Can the chisel
bit actually be used for making round (or close to round) holes?

Rough it out maybe 1/2" undersized and clean it up. It's masonry
work, it's going to be rough.
