摘要： A roller cone drill bit includes a bit body adapted to be rotated about a longitudinal axis. At least one leg which terminates in a shirttail portion depends from the bit body. The shirttail portion defines a first end face having a first circumferential groove thereon. The first circumferential groove has a radius equal to the radius of a tip of the shirttail portion. A journal is cantilevered from the leg, and a roller cone is rotatably mounted on the journal. The roller cone has a second end face adjacent to the first end face. A second circumferential groove is formed on the second end face.

摘要： A roller cone drill bit includes a bit body adapted to be rotated about a longitudinal axis. At least one leg depends from the bit body, and a journal is cantilevered from the leg. A roller cone is rotatably mounted on the journal. A cone retention member is disposed between a first slot in the journal and a corresponding second slot in the roller cone. An access hole runs through the journal to the first slot, penetrating the first slot at a location away from the top dead center of the first slot.

摘要： A fixed-head drill bit includes a bit body having a plurality of cutting elements and at least one wear knuckle disposed on the bit body. Each cutting element includes a cutting surface defining a swept cutting profile when the bit is rotated about an axis. The at least one wear knuckle is positioned at least partially within and extending at least partially outside a selected one or more of the swept cutting profiles, allowing the fixed-head drill bit to wear into a more stable configuration.
