Good god dude. Go .0625" at the most per pass but with that low of RPM I would suggest .030" for better results. 2 flute carbide works better than 4 flute as 4 flute cloggs up in copper. 3 flute is actually ideal as it keeps a better balance but they are hard to find. At utabintarbo pointed out solid carbide is the way to go. I just switched from HSS to carbide and will not go back.
