I am rigid tapping some 5mm holes in 6061 in blind holes to 11mm depth. No coolant, just tapping fluid on the tap and in the holes. I programmed the speed at 500, forgetting that the retract speed is twice that. It worked fine but is that too fast for safety? If I break a tap, it'll be extremely difficult to get out, given the location. I am using an Emuge Tin spiral tap in my tapping head.
