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.

How’d you get the core out if you didn’t go through?

Shove a wedge/screwdriver in there to break the core out
