I repair office machines and one of my customers has a rolling cart they lost the key for, and they now want use the stuff in that cabinet.....

I tried getting keys from the cabinet supplier but they didnt work...

has anyone ever drilled out a lock?

I would rather avoid damaging the cabinet much. and other than flip or flop have never seen anyone drill out a lock. on flip or flop they just start drilling, but never show what happens.
