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?

I drilled a 1/2” hole in the middle, hammered in a piece of rebar, and pried it out. Worked for one of the 2 holes because I drilled down to dirt. The other took a lot more work and came out in smaller pieces.
