I'm sure this has been discussed before but I can't find it in a search. When making a Profile Cut out of a circle or anything really that requires several passes, I have this indentation from where the End Mill plunges. It's not deep, maybe 1/64" and It can be sanded out but then what I'm cutting isn't precise anymore.

To reduce the cutting forces: Choose a light cutting geometry, L, with a sharp edge, and a grade with a thin coating. Use inserts with small corner radii and small parallel lands. Sometimes adding more damping to a system can decrease the vibration tendencies. Use a more negative cutting edge geometry and a slightly worn cutting edge.
