If you want nice round hole and the drill bit not to jump/walk on you when enlarging the hole, get something like this: http://www.amazon.com/IRWIN-10502ZR-...win+step+drill Put some masking tape on the carbon fiber that you are drilling, use light pressure and let the bit do the work. Works extremely well. Good luck.
