Tinker,
No, the small hole gages are either ball end or half ball end and the appropriate size should bridge the groove. They are limited to 1/2" holes. You are thinking about the much larger "T" shaped ones that go to well over 3". Note I said "decent" measurement, I concede it may be a fraction of a thou. off.
