FIELD: mining engineering.
SUBSTANCE: cutting element for the drilling tool includes a substrate and an array of superabrasive material located on the substrate. The array of superabrasive material has a nonplanar front cutting edge with sharpened shape, including a conical side surface and a dome shape end. The substrate has cylinder shape, which maximum diameter is smaller than the maximum diameter of the array of superabrasive material. The solid contact boundary between the substrate and the array of superabrasive material is located behind the conical side surface of the nonplanar front cutting face of the array of superabrasive material along the central axis of the shaped cutting element. The cutting element further includes at least one recess, extending into the conical side surface of the nonplanar cutting face of the array of superabrasive material from the front cutting face.
EFFECT: increased cutting efficiency.
