Hi Bob,
Like Michael i would start at 710, although you may find the slower speed with a higher feed may work better in the end, just to give the motor a bit more leverage. If i was too attack it on the Antrac i would probably run at 1200rpm, feed of .25mm and a DOC of 2mm. But I have 5hp to put to use, not 2.
The other thing to try might be a Cermet insert, there is a guy on ebay with some Kyocera inserts, i have been using the CCMT's to good effect.
The other thing is what sort of chip breaker has the inserts your using have? Is it just a straight one or is it "wavy"? The waves are there to interrupt the chip flow and help break it up.
