    摘要: A cutting element includes a sleeve, a rotatable cutting element, and at least one retaining ring. The sleeve has a first inner diameter and a second inner diameter, wherein the second inner diameter is larger than the first inner diameter and located at a lower axial position than the first inner diameter. The rotatable cutting element has an axis of rotation extending therethrough, a cutting face, a body extending axially downward from the cutting face, wherein the body has a shaft that is disposed within the sleeve, and a circumferential groove formed around an outer surface of the shaft. The at least one retaining ring is disposed in the circumferential groove and extends at least around the entire circumference of the shaft, wherein the at least one retaining ring protrudes from the circumferential groove, thereby retaining the rotatable cutting element within the sleeve.

    摘要: A drill bit assembly that includes a shank including a shank axis, first and second ends, a drill bit seat at the second end and a central flow bore extending axially from the first end. Additionally, the assembly includes a sleeve disposed about and translatable axially relative to the shank and a drill bit rotatably coupled to the sleeve. The drill bit includes a first bit face having a first cutting structure configured to engage an earthen formation, and a second bit face having a second cutting structure configured to engage the earthen formation. The drill bit is configured to rotate about the about the shank axis in a cutting direction, and to rotate about an axis of rotation being orthogonal to the shank axis to selectively expose the first or second cutting surface to the earthen formation. The seat is configured to receive the first or second bit face.

    摘要: A formation-engaging assembly includes a formation-engaging structure holder with a side surface between a proximal end and a distal end, a receptacle in the distal end, and a lateral protrusion extending from a portion of the side surface of the formation-engaging structure holder adjacent the distal end. A formation-engaging structure may include a formation-engaging surface at a distal end, a proximal end and a sidewall therebetween. The proximal end and at least a portion of the sidewall of the formation-engaging structure may be received within the receptacle of the formation-engaging structure holder. Earth-boring tools may include such formation-engaging assemblies.
