I would question the grade of mild steel as Eric says, there are too many grades of mild steel which will affect the cutting speed. That said, 1600 rpm isn't necessarily wrong! Depth of cut and rigidity of the tool and work holding can cause excessive cutter wear or breakage. Explore all avenues but try to find the type and quality of the material you are cutting.

Just to add to the 3 or 2 flute cutters thing, yes 2 flutes are easier to regrind, they also have more clearance for swarf removal, they are also weaker than 3 fluted cutters. Buy the best quality you can or source from production engineering friends if possible, they will not use rubbish (I hope!!!!). I could recommend some manufacturers but don't want to be biased towards any one of them.

I hope you find your solution to your issues.
