I had one like that where the actual hole for the 2" tap was about the size of a finger. Seems that once the contractor doing the wet tap hit water he thought he was done.
I've done many wet taps through the years and always made measurements and marked the machine to make sure that I got the bit deep enough (without going through the other side of the pipe).
