rpm = fpm*12 / pi*D so for a HSS cutter of 0.5", a 750 fpm, that gives an rpm of ~ 5900 ! (this seems too fast) Feed = ftr * T * rpm using ftr of 0.016, 4 flute end mill gives a feed rate of 367 inch/minute are these correct? what values are "reasonable"?

Then drop feed by 10 to 15% and you should be fine. I have used 1/8" up and down shear at 18000 - 20000 and usually run 1/8 to 1/4" deep passes multiple times. 150 to 180 IPM works for me, depending on depth of cut and flute length, a long flute out of the chuck makes the bit more delicate, shorter is stronger.
