For machining mild steel we use 4 flute end mills, stainless we go up to five flutes. Again though, these are all run in our VMC and they are solid carbide.
For what you're trying to accomplish in a knee mill, I would stick with HSS for roughing and then if the tolerance and finish calls for it, go with a carbide to finish. I always climb milled in my Lagun for my finish, but kept the finish pass to approx. .005" and kept the binders on the axis' snug to prevent the table from jumping due to backlash.
My Lagun FT2 Knee Mill.
My youngest boy Christian milling a keyway in a shaft. Back then probably around 14-15, now he's 20! Geez......how time flies!!
