    • An exemplary cutting element for a rotary drill bit may have a forward end and a rearward end. The cutting element may include a substrate having a forward face, a rearward face, and at least one interface surface extending between the forward end and the rearward end. At least one of the forward face and the rearward face may be a substantially planar surface. The cutting element may also include a superabrasive layer bonded to the at least one interface surface of the substrate. The superabrasive layer may include at least one cutting edge extending between the forward end and the rearward end. An exemplary rotary drill bit may include at least one cutting element coupled to the bit body. The at least one cutting element may have a rearward end adjacent to the bit body and a forward end extending away from the bit body.
    • 用于旋转钻头的示例性切割元件可以具有前端和后端。 切割元件可以包括具有前表面,后表面和在前端和后端之间延伸的至少一个界面表面的基底。 前表面和后表面中的至少一个可以是基本平坦的表面。 切割元件还可以包括结合到基底的至少一个界面表面的超级磨料层。 超级磨料层可以包括在前端和后端之间延伸的至少一个切削刃。 示例性旋转钻头可以包括联接到钻头体的至少一个切割元件。 所述至少一个切割元件可以具有与所述钻头体相邻的后端以及远离钻头体延伸的前端。
