Iam trying to drill a series of holes using a brad point drill bit.
When the bit retacts to the top of hole it does this crazy thing and
enlarges the top part of hole.


Are you sure the brad point is not slightly deflecting the drill, when it is
entering the surface? If it does that when it comes out of the slightly
offset hole, the edges will hit that offset hole and wobble, and try to cut it
larger.

Just my guess,
