Much better feel than a Tapmatic

Agreed, vastly better feel. I tapped a couple hundred 0-80 holes, .240
deep in 304SS using roll taps. Hole was .250 deep at full dia. This was
at my last job, and I brought in my own head. My boss was aghast at what
I wanted to do, citing the cost of a 10" conflat flange. But I didn't
break a single one and saved a day's labor over hand tapping the way
they'd been doing it.

Just don't -ever- bottom a tap with a Procunier...

Though in fact, I have done so with larger taps and was able to react
quick enough to not break the tap. In fact, have never broken a tap with
a Procunier.
