Tapping 4-40 on CNC
I have posted regarding this subject before, but I would like to know what tool holder shops are using to form tap 4-40 in 6061. I have done quite a bit of research, but can't pinpoint which holder would be the best for this application. Or should I run solid with a collet? My machine is older, but does have the tapping autocycle.
Any help is greatly appreciated.
Thank you
