If you do not have a center punch to start with and have to start with a smaller bit, then make sure that that bit is SMALLER than any brad point you are thinking of using after starting the hole. The last thing you want is to NOT have any meat for the brad point to guide from. If you have eliminate all of the material around the brad point it won’t center properly.
