Abstract
A well tool drilling tool can include a torque transfer mechanism with an inner mandrel, an outer housing, and at least one pawl which displaces radially and thereby selectively permits and prevents relative rotation between the inner mandrel and the outer housing. A drill string can include a drill bit, a drilling motor, and a torque transfer mechanism which permits rotation of the drill bit in only one direction relative to the drilling motor, the torque transfer mechanism including at least one pawl which displaces linearly and thereby prevents rotation of the drill bit in an opposite direction relative to the drilling motor.
