Does anyone know how large of a thread can be roll form tapped and how well does it work in cold rolled steel and stainless and brass for that matter?
I have used roll form taps in the past but only in aluminum and sizes less than 1/4".
I also wonder about using them in a comp/ret tap driver in my VF-2.
I'll bet at least one of you guys has experimented with all of the available options.
I'm trying to first elminate digging chips out of blind holes, and second, cut down on tap breakage. Seems like I heard somewhere that roll form taps take less torque and provide a better thread.
Any experiece in this area would certainly be of help.
Thanks:wave:
