Start about 1000 RPM. I tap 5/8-11 at 400RPM 1 1/4" deep in steel in a lathe > What type of tapping cycle should I use, > Continuous, or some type of peck cycle. Tap it in one shot if you are using a spiral point or a spiral flute tap. If you are using a straight flute tap then tap one diameter deep maximum then finish by hand.
