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： An expandable tool includes a body and a recess extending at least partially through the body from an outer radial surface of the body. A spline insert may be at least partially positioned in the recess and coupled to the body. The spline insert may include a single spline or multiple splines. A cutter block or other expandable member may be at least partially positioned in the recess. The cutter block or other expandable member may include a spline on a side surface thereof, which spline may be engaged with the one or more splines of the spline insert. Engagement between one or more splines of the spline insert and spline of the cutter block or other expandable member may allow the expandable member to move radially outward from a retracted position to an expanded position, and vice versa.

摘要： Methods for joining an ultra-hard body, such as a thermally stable polycrystalline diamond (TSP) body, to a substrate and mitigating the formation of high stress concentration regions between the ultra-hard body and the substrate. One method includes covering at least a portion of the ultra-hard body with an intermediate layer, placing the ultra-hard body and the intermediate layer in a mold, filling a remaining portion of mold with a substrate material including a matrix material and a binder material such that the intermediate layer is disposed between the ultra-hard body and the substrate material, and heating the mold to an infiltration temperature configured to melt the binder material and form the substrate.
