Ok I am new to the machining community and I bought one of these cheap $50 facemills from Ebay. It uses 1604 inserts. So I am having some issues using it and wondered if you folks could point me in the right track.

I tried to use this on a piece of steel and no mater spindle speed of feed rate could I get the chips not to be red on fire. The surface finish sucked bad. So I figure the inserts suck, but before I buy a more expensive set, could the facemill just suck as well. I mean being new to the hobby it seems the facemill is just a found holder of such. Also if it take 1604 inserts is that all it can take?

I am using a X2 style mill so what should be my spindle speed etc using this..

This is very similar to what I bought:
