For harder materials, machinists will also prefer 2 flute micro-mills, even in materials such as steel where they're used to having 4 or more flutes in conventional milling. The reason is that micro-milling produces a larger volume of chips than conventional milling and fewer flutes provides larger gullet space. But there's a trade-off.
