New to working with oak, red oak in this case, and I used a 3/8 round over bit with bearing and the surface was burned. Not 100% but something like 10-20% of it. Sanded most of it out but that was not fun...
The tool, although a box store special set with 3 sizes, feels sharp to my finger with no visible damage. Does well with pine/spruce (softwoods). I had the router (a big Bosch) pretty high speed but feed very slowly with one pass.
I know I did something wrong but which is most likely causing my burning? Slow the router, crappy bits or should I have taken multiple passes?
I don't have much stock for testing. Pretty much used up what I had on hand or more precisely what my son left when he moved out...
