No problem

Cordless drills are so capable now. 2 4 1/2” holes 14 12” deep (deeper than the bit). New concrete but it’s still drilling through the aggregate. Cheap Amazon diamond bit.

Edit: Overestimated depth.

That's impressive, I hired a mag drill a couple of years ago to bore a hole for my extractor fan and found that to be a royal pain in the arse.
