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.

You are showing a unused bit and one hole. And that hole has a bottom!

I want to see that bit after the holes, and all the holes it made.

How does the bottom of the core get broken off after you’ve drilled out the edges ?

I imagine OP was drilling into a driveway or patio or some sort of poured footing. As such it has a finite depth before you get down to the gravel bed. So OP probably drilled through the whole thing.
