I was rummaging through my tap collection and came across a couple of
forming taps. I have no idea how they got there, but there they were. Now,
the question is: where are they better used than cutting taps? Since they
are more particular about the hole size, I won't use them unless they have
some advantage.

Thanks,
Bob

I wonder how forming taps would work in punched holes to maximize the amount
of thread created.
