Have you tried going in each direction? Typically, one direction will chip and the other one won't. I believe you want the bit turning in toward the wood not out away from it.

I am using a 1/2 inch spiral carbide up cut bit from McMaster Carr (27395A31). Is there a better router bit I can be using here?
