Abstract
A drill bit made according to one embodiment includes at least one of a weight sensor and a torque sensor configured to provide signals representative of the weight and torque on the drill bit when the drill bit is used for cutting into a formation. A circuit may be configured to process signals from the weight and torque sensors to provide an estimate of the weight and torque on the bit when the drill bit is used for cutting into the formation.
