Abstract: A cutting element includes a substrate that is axially symmetric about a central axis. The substrate has a radius perpendicular to the central axis and that extends from the central axis to an outer surface of the substrate. A super-hard material is coupled to the substrate, and the central axis passes through the super-hard material. The super-hard material has an external surface defining at least one ridge protruding from a remainder of the external surface. A central point on the central axis is offset from the external surface of the super-hard material by a distance equal to the radius of the substrate. A distance measured from the external surface of the super-hard material to the central point is greatest at a position between 25° and 45° from the central axis of the substrate.

Abstract: A bolster for a degradation pick includes a transverse cross section that is non-circular. Non-circular cross sections include square, triangular, hexagonal and other shapes. The bolster is made from a wear and/or erosion resistant material. The wear and/or erosion resistant material helps to protect the shank of the degradation pick. The bolster has a matching shape to the shape of the shank of the degradation pick.

Abstract: A tool for removing material includes a body, an ultrahard insert, and a matrix. The body has a forward portion, an opposing rear portion, and a longitudinal axis therebetween. The ultrahard insert includes an ultrahard material, and the ultrahard insert is mounted to and contacts the body proximate the forward portion. The matrix contacts the body and the ultrahard insert. The matrix is mechanically interlocked with the body and at least a portion of the matrix is positioned circumferentially around at least a portion of the forward portion of the body.
