摘要： Methods for attaching cutting elements to an earth-boring bit rely on keying the cutting elements inside cavities formed in the earth-boring bit. The attachment methods may involve specific shapes of the cutting elements and the cavities in which the cutting elements are received, and/or mechanical retainers. Preferably, the blade of the earth-boring bit is thicker around the opening in the edge of the blade than when the cavity is shaped for receiving a cutting element that has a circular cross-section.

摘要： An earth-boring tool comprising a bit-body, a blade, and a cutting element assembly. The cutting element assembly comprising a journal, a rotatable cutting element, and a retention element. The journal defines an upper cylindrical exterior surface, a first bearing surface that intersects the upper cylindrical exterior surface, and a first external groove in the upper cylindrical exterior surface. The rotatable cutting element comprises a table of polycrystalline hard material having an end cutting surface and a supporting substrate. The substrate defines a second bearing surface, a longitudinally extending blind hole having a diameter larger than the diameter of the upper cylindrical exterior surface of the journal, and a second groove in the surface of the substrate defining the blind hole. The retention element is disposed at least partially in the first groove and partially within the second groove.

摘要： A method of forming a supporting substrate for a cutting element comprises forming a precursor composition comprising discrete WC particles, a binding agent, and discrete particles comprising Co, Al, and one or more of C and W. The precursor composition is subjected to a consolidation process to form a consolidated structure including WC particles dispersed in a homogenized binder comprising Co, Al, W, and C. A method of forming a cutting element, a cutting element, a related structure, and an earth-boring tool are also described.

摘要： For drill bit cutter indexing, a housing is disposed in a drill bit. An indexing cog is in physical communication with a cutter and interlocks with the housing in a first index position of a plurality of index positions in response to a first compressive load applied to the cutter. A motivator disengages the indexing cog from the housing and positions the indexing cog to interlock with the housing at an initial second index position in response to a removal of the compressive load from the cutter.

摘要： A cutting element for use in a drilling bit and/or a milling bit having a cutter body made of a substrate having an upper surface, and a superabrasive layer overlying the upper surface of the substrate. The cutting element further includes a sleeve extending around a portion of a side surface of the superabrasive layer and a side surface of the substrate, wherein the sleeve exerts a radially compressive force on the superabrasive layer.

摘要： Polycrystalline diamond compact (PDC) cutting elements include leached and un-leached regions. The leached region may be or include a leached annular region. An inner boundary of the leached annular region remote from a side surface of the polycrystalline diamond may have a non-linear profile in a plane extending through the PDC cutting element along a longitudinal axis of the cutting element. Methods of forming PDC cutting elements include configuring polycrystalline diamond of a PDC cutting element to have such a leached annular region with a non-linear profile. Earth-boring tools may be formed that include such PDC cutting elements.
