Agree with others about using a rougher and feed being too slow. If it were me, I would run that carbide cutter around 1300 rpm and .250 DOC. Feed would be whatever felt comfortable and produced good chips. In general, I run carbide at about twice the speed of HSS. I'm not on the clock and the cutters come out of my pocket. It's fun to see how far you can push it, less so when it's your dime.
