摘要:
A drill bit system for a drilling assembly is disclosed. The drill bit system may include a chassis, a head, and a first plurality of gauge pads. The chassis may be configured to be operably coupled with a first rotational motion source. The head may include a first plurality of cutters coupled with an end of the head, and the head may be rotatably coupled with chassis. The head may be configured to be operably coupled with a second rotational motion source. The first plurality of gauge pads may include a second plurality of cutters, and the first plurality of gauge pads may be fixedly coupled with the chassis.
