I cannot comment on the inserts because I am not familiar with them but I think the speed is a bit high and the feed a bit low. Machining stainless at 0.002" per tooth means each insert is cutting in the work hardened surface created by the preceding insert.
My approach would be to take the speed down to 200fpm and bump the feed to 0.005" per tooth, maybe even a bit higher if you have the torque available.
Also lose the coolant and go with a strong air blast. In addition to work hardening badly with a slow feed you are probably thermally shocking the inserts and get micro-chipping.
