Drill bits are flexible by design.
You just want to establish the center point with a center drill bit. This is how it looks like: http://mini-machine.com/tooling-cent...rill%20set.jpg
After that the normal drill bit will find the center and do what it is supposed to do.

clyde just what kerst said . I tend to drill the hole a little smaller then finish it with a boring bar , drill bits tend to deflect a little

For nice clean and accurate holes one can use a reamer to finish the hole.
