Abstract
A drill bit is provided that in one embodiment may include a blade profile having a cone section and one or more cutters on the cone section configured to retract from an extended position when an applied load on the drill bit reaches or exceeds a selected threshold. The drill bit is less aggressive when the cutters are in the retracted position compared to when the cutters are in the extended position.
