What? There is another small hole matching the chip width on the 2"
diameter?

Essentially, the 2" hole was directly over a smaller 1/4" hole. Thus, the
chip never could form in a 360 degree situation. Every time the cutter got
to the 1/4" hole area, the chip ceased to exist for a small amount of time
and thus broke off, spun off and disappeared.
