Did they offer you a different bit to try?

Wet core drills work great, I honestly don't know how you sheared any "teeth" off, the face of them is almost flat. A dry core drill on the other hand, I've sheared lots of teeth off and ruined lots of bits, usually when I hit rebar. A wet core will drill anything and not look back.

I wouldn't give up on them from one bad experience, the bit might of been defective or cracked from the last job. Maybe nobody noticed....
