I'm looking to se up a customer performing a roll form tap operation on M8 x1.25" holes.
CRS, 0.300" thick.
I'd love to know the RPMs you would run for a conservative process, minimal coolant (not flood), etc.
My conservative number for a cut tap would be around 300-400 RPM. I'm guessing a roll form tap runs slightly different numbers (HSS tooling).
Any input would be greatly appreciated.
