139 in/lbs. You can look at the specs at this link: http://www.haascnc.com/Promos/Prod_B...index.htm#/39/
I have no problem cutting 4130 with a .5" end mill. Drilling sucks, I stalled with a .5" drill at 535 rpm and 3 ipm. Haven't taped with it but if I had to guess I'd say no bigger than .375-16 in 4130.
