Yes the hole is chamfered and using a floating holder. Looking for 40% thread to a loose fit.
Are you running a 10-32 tap, and just trying to feed it 4 times as fast?
Looking for info to tap a 8-32 Quad Lead H3 into 303 stainless. (Drill size, speed and feed per rev) on our Mazak Multi 610. Taps keep braking on contact at .125 per rev.
Thanks
Thread milling sounds like it would be easier.
I don't think a 4 start #8 thread could be thread milled. Seems the thread form would be all wonky because the lead is too high.

Not sure how it would look. I guess when I’m not sure how a tap will work I hand tap the first hole and see how it feels then decide on feed n speed. It would be nice if there was a #8-8 tap then you could rigid tap to depth 4 times and bump the R plane up 1/32 each time and drop the Z the same amount.
Not necessarily but probably, the angle is going to be too steep. In a lathe you can tilt the tool over far enough so it doesn't rub on the thread and run it though along the thread but in a mill, it has to rotate around the spindle axis while making the thread, so probably going to have severe interference problems on the heel.Why not single point the thread?
Why not single point the thread? with such a coarse pitch you'd have to have a threading bar that was relieved underneath the cutting face so it didn't rub.

But one could always try ...
Tap seems the easiest to me.
It would have a tiny little shank.. If everything was perfect, the biggest the shank could
be is .115.. probably end up around .090" for clearance. It would just be miserable..
But I thought a Mazak multi 610 was a lathe?
