is overrated
When does it cease to be chamfering, and start becoming porting....?
.
When there is no longer a clean break/line defining the transition from the surface 90 degrees perpendicular to the face of the hole you started on.

The real question is; How long does it take a wood boring beetle, wearing rubber boots, to bore a 1 inch diameter hole through a 5lb. block of Ivory soap, in a light rain?
