Core drilled through about 8 inches of brick and poured concrete.

Drilled a nice core through brick. Got harder when coring through poured concrete. I realize that it is not recommended to core through poured concrete, but this eventually did the trick. Took about an hour of drilling (drill only, no hammering with drill). Glad I found a dry core solution that solved my problem!
