I would run about 60 surface feet per minute (sfm) and use either water
based coolant or a mister with coolant in it. You could run faster but
it will save the tool to run at 60 sfm. You could also use sulfur oil
and either mist or paint it on the cutter. The final decision of speed
comes from looking at the color of the chips and how much heat you are
generating, all revelent on the sharpness of the tool, the type of
coolant and the sfm of the cutter. To get the most life out of the tool
you want the chips to come off shiny with no discoloration and the
coolant not steaming from the heat.
