I was rummaging through my tap collection and came across a couple of

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,

I used them for threaded arbors on mini-grinder cup brushes. They take
two to three times the horse power but no chips. They always tell you
when they are too dull....SNAP!
