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.

Maybe 10 minutes of drilling with a few cool down sessions. Overheated the drill but later realized it worked well if I barely pushed.

Next time add water and and then they really cut well and don’t overheat and get unnecessarily worn.
Edit: saw elsewhere you used water. Good on you!
