You might want to use a slightly smaller bit with the hammer drill because
holes usually come out large.

With a hammer drill and the right bit you can do it for sure.

We originally planned on going in the side, but through the floor is much
more direct with no need to run a pipe on the outside wall of the house.
Do you think it's possible/wise to continue drilling?

There could be a steel pan filled with concrete under the firebox and
in front of it. My gas pipe goes out the side and I think that is
where gas logs and inserts expect it.

We have a woodburning fireplace we are converting to gas logs. I am
trying to drill a hole to accommodate the gas pipe through the floor
in a front corner of the firebox to a utility space under the house.
I get through the firebrick, about 3 1/2", and then hit something my
carbide bit cannot penetrate.

Does anyone have a suggestion how to detect what I'm hitting? Do
they use steel plate reinforcement in fireplace construction? Any
help is appreciated.
