They are useful for a range of pitches, you cannot use just one for everything; the nose radius is small enough for the finest pitch in the range but not too small for the largest. You turn the OD slightly smaller than what would be the case for a full profile thread and the end result is a flat topped thread. Don't ask me how much the 'slightly smaller' is, I just do it by guess.
