bottoming tap, when to use?
Maybe I'm just old school, but I was taught never to start threading
with a bottom tap. Use plug or taper first then finish with a bottom tap. But as I am shopping for 1/4-20 taps with sprial flutes it seems bottom stlye is most popular. Can I really run a bottom tap into steel? VMC with rigid tapping and flood coolant. I usually buy modified bottoming if I can. Plug seems even harder to find. Remove 333 to reply.
