Because of the varying diameters of tapered endmills speeds and feeds cannot be accurately recommended. Run the endmill at the highest possible speed that does not produce heat-discolored chips. Feed the cutter slowly enough to let the cutter produce chips, but not to heavily where you could cause tip breakage and flute chipping. To calculate large diameter take .0349 x's the flute length and add your tip diameter.
