Inconel question

Recently just started working with inconel and it has been rough to say the least(already missing aluminum). Is there any advice any of you could offer? Stuff like feeds, speeds, how much to take off a pass, tooling, etc.

Currently using a 1inch 3 tooth carbide face mill to get a 2x1.5x.25 blank to size. Currently running it at 2000rpm, feed of 6, taking off .005 a pass, but that just doesn't feel right/optimized because it is eating my inserts. I have to take it down .125 and it's going to take like 20min a part, but when I try to speed the feed rate it seems to eat the inserts faster. Is there an online calculator or another suggestion you would recommend?

Thanks in advance!
