Abstract
A tubular body with an axial bore includes an upper connection attached to a drillstring and a lower connection with a drill bit disposed thereon. Primary and backup cutter blocks are coupled to the tubular body and configured to selectively expand radially therefrom. An activation system within the tubular body is configured to selectively expand and collapse the primary and backup cutter blocks in response to changes in weight applied to the primary and backup cutter blocks.
