Abstract
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.
