摘要： Cutting elements for earth-boring tools include one or more recesses and/or one or more protrusions in a cutting face of a volume of superabrasive material. The superabrasive material may be disposed on a substrate. The cutting face may be non-planar. The recesses and/or protrusions may include one or more linear segments. The recesses and/or protrusions may comprise discrete features that are laterally isolated from one another. The recesses and/or protrusions may have a helical configuration. The volume of superabrasive material may comprise a plurality of thin layers, at least two of which may differ in at least one characteristic. Methods of forming cutting elements include the formation of such recesses and/or protrusions in and/or on a cutting face of a volume of superabrasive material. Earth-boring tools include such cutting elements, and methods of forming earth-boring tools include attaching such a cutting element to a tool body.

摘要： An earth-boring tool may comprise at least one cavity formed in a face thereof. At least one retractable pad residing in the at least one cavity may be coupled to a piston located at least partially within the at least one cavity. Additionally, a valve may be positioned within the earth-boring tool and configured to regulate flow of an incompressible fluid in contact with the piston through an opening of a reservoir. A cartridge may comprise a barrel wall defining a first bore, and a piston comprising at least one retractable pad positioned at least partially within the first bore. The barrel wall and the piston may define a first reservoir within the first bore, and a valve may be positioned and configured to regulate flow through an opening to the first reservoir. Related methods and devices are also disclosed.

摘要： In an excavation tool according to the present invention, an excavation tip is attached to an outer peripheral portion (gauge surface) of a tip surface of a tool main body to be rotated about an axis. The excavation tip is inclined such that the excavation tip is directed toward an outer peripheral side of the tool main body and a tool rotation direction side as a centerline of the tip is directed toward a tip side in an axial direction, and a planar seat surface perpendicular to the tip centerline is formed in the outer peripheral portion of the tip surface of the tool main body such that the seat surface is adjacent to at least the tool rotation direction side of an attachment portion for the excavation tip.

摘要： According to an aspect of a drilling tool of the invention, the drilling tool includes a circular-cylindrical casing pipe (1); an annular ring bit (2) that is disposed at a leading end of the casing pipe so as to be coaxial with the casing pipe and rotatable around a central axis (O) of the casing pipe (1); and a pilot bit (4) that is inserted into the casing pipe (1) from a rear end side and has a leading end disposed at an inner peripheral part of the ring bit (2). The ring bit (2) is engaged with the pilot bit (4) in a rotational direction during drilling, and thereby is rotatable integrally with the pilot bit (4) around the central axis (O) and is locked to the leading end of the pilot bit (4) in a direction of the central axis (O). Drilling tips (5, 3) are mounted on the leading ends of the pilot bit (4) and the ring bit (2) so as to protrude therefrom, and drilling tips (5A) positioned at an outermost periphery of the pilot bit (4) and drilling tips (3A) positioned at an innermost periphery of the ring bit (2) overlap each other in a rotational trajectory around the central axis (O) during drilling.
