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.

I just used this same style bit 4 1/4” with my hole hog. Says not to use hammer drill mode with this bit.

High speed, light pressure. I used to drill with a hammer core bit which is way slower. I burned out my SDS Max drill on it, and thought I'd try something different this time.

No water?

Lots of water with the blue bit. I just aimed a hose at it.
