Here is an example I found to explain the idea. The holes circles in purple/pink appear to be chamfered (it is possible that this was not done on purpose in this photo - I'm not sure where it came from). The other holes are not chamfered. If cross drilled rotors are for racing application, they should be chamfered to reduce the likelihood of cracking. Of course, the best solution is to have the holes cast in place when the rotor is cast.
