Forgive me if I missed the following suggestion. I read thru the replies really quick.
I agree, if you have a 2mm corner, you want a tool smaller than 4mm. You want to "drive the tool around the inside corner radius" rather than "plow into it and change directions"
If you already have the 4mm tools, a couple things you can and should do:
1: drill the corners. Maybe stay a couple thou away or drill smaller. but do that
2: Finish each depth with the shortest tool you can manage, you may need a few tools
3: MOST IMPORTANT AS I DIDN'T SEE IT MENTIONED YET (if it was, i'm sorry). You say you have a 2mm corner radius, but what is the tolerance of your radius? Lets pretend you have +/- .3mm on the radius. USE IT. Program the corner to be 2.3mm, and use your 4mm endmill to interpolate around that radius rather than plow into it
