Collin brand new cheap can be part of your problem. I had that happen to me about two weeks ago. Another thing is use another piece of wood right behind the piece your routing. That should solve the problem.Building 3 corner shelves. Giving each a profile.
The first two went fine. But the third .... The bit grabs and tears it up.
