Alan, You're right ... chipping, while cutting the notch, is an occasional annoyance that is usually fixable with a hand file. However, I recently swapped my tired old straight-flute for a spiral-flute bit. Does the old expression ... 'like a warm knife through butter' bring about a welcome image? Try it ... these bits aren't that expensive and are simply perfect for this application. BTW David, in the entire keytopping procedure, the hand file does not make an appearance until the final 20 minutes or so. It is used only to take the sharp edges off the machine-trimmed plastic.
