Tapmatic Tricut cutting fluid made by LPS. It's what I use when tapping, and was handy. HSS and 70RPM, cutter 60*, releived 5*+ on leading edge, 5*- on trailing edge. Compound set on 29.5*. The thread was rough when I was feeding with the compound, I watched Tom'sTechniques on Youtube and he starts off feeding with the compound, and the last few cuts he feeds with the cross feed. I tried it, and cut the best threads I've ever cut.
