Unless you have split point drill bits the half inch bit isn't going to do well starting a hole. I would drill a pilot hole large enough to overcome the non cutting center portion of your drill bit (assuming non split point). This will help with bit walk when starting the hole. Too large of a pilot hole will cause the 1/2" bit to grab when enlarging the hole.
