摘要:
In an aspect, drill bit for use in drilling a borehole is provided that includes a body including a side, face section and a passage in the body. The drill bit further includes a rubbing member disposed in the face section and configured to control a depth of cut for the drill bit, wherein the rubbing member comprises a thermally responsive material in thermal communication with the passage configured to control a position of the rubbing member with respect to the face section.
