I tap 0-80 on a Haas VF3
In actual fact, a cnc is a good way to
not break delicate taps. I use rigid tapping now, of course.
However, before that, I used ER16 floating tapping heads for thousands of holes, most from 0-80 to 6-32, on older Bandit style controllers. Really had no problems doing it. However, the light springs in the ER floating holder might make form tapping unreliable. I never did form tapping back then, but it takes a little bit more jam to make the form tap bite and start, and I do not know how consistent that would be from hole to hole. In blind hole tapping, one thing you want, is extreme consistency in tool performance.
