This is a bad strategy. You should always aim to have your fillets larger in radius than your bit radius unless you really have no work around. The reason for this is because endmills do not like going into a corner stopping, then changing direction. They would be much happier and will give a better finish and less likely to break in corners if they arc through it a little.

I would suggest 0.075"-0.090" radii for an 1/8" endmill.
