I was looking at the graph that they posted in the Carbide link.
But I found a new link below and it now translates to 27.5 mm/s.

But with that said I will do the 1/8" single flute end mill with a 8-15 mm/s feed rate.
But would it also make sense to turn down the 660 to prevent melting of material with the bit? I have made one of the DIY speed controls ready to rumble.
