    Abstract: 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.

    Abstract: An example drill bit is formed by a bit head portion and a shank portion. The bit head portion includes a bit face, and the shank includes a bit portion and a bit connection. The bit connection is configured to be coupled to a drill string. The bit head and shank are configured to be secured together. When secured together, one or more blades that start near a central axis of the bit face continue to a gage portion of the bit and along at least a portion of the length of the bit portion of the shank. One or more anchoring elements are coupled to the bit head and the shank to restrict relative rotational or axial movement between the bit head and the shank.

    Abstract: Diamond bonded construction comprise a diamond body attached to a support. In one embodiment, an initial substrate used to sinter the body is interposed between the body and support, and is thinned to less than 5 times the body thickness, or to less than the body thickness, prior to attachment to the support to relieve stress in the body. In another embodiment, the substrate is removed after sintering, and the body is attached to the support. The support has a material construction different from that of the initial substrate, wherein the initial substrate is selected for infiltration and the support for end use properties. The substrate and support include a hard material with a volume content that may be the same or different. Interfaces between the body, substrate, and/or support may be nonplanar. The body may be thermally stable, and may include a replacement material disposed therein.

    Abstract: Methods for manufacturing a matrix tool body comprising placing a first matrix material within a first region of a mold cavity proximate a surface of the mold. A second matrix material may be placed within a second region of the mold cavity positioned inwardly of the first matrix material. The first matrix material and the second matrix material comprise a plurality of hard particles. The plurality of hard particles of the second matrix material have a median particle size that is less than the median particle size of the first matrix material. The plurality of hard particles of the first matrix material and the second matrix material are infiltrated with an infiltration binder to form the tool body. Also included are tool bodies having one or more regions proximate a surface of the tool body comprising an erosion resistant matrix material and/or a wear resistant matrix material.
