发明名称 INNOVATIVE CUTTING ELEMENT AND CUTTING STRUCTURE USING THE SAME
摘要 A cutting tool is disclosed that includes a tool body, a plurality of cutting element support structures extending from the tool body, at least one slot formed in at least one of the cutting element support structures, a cutting element having a diamond shearing element with a plurality of surfaces, and at least one mechanical retention mechanism adjacent to the cutting element. Each cutting element support structure has a leading face, a top side, and a trailing face, and the slot has two side surfaces, each side surface terminating at the leading face and top side of the cutting element support structure. Each surface of the cutting element has two dimensional values, wherein the cutting element is positioned in the at least one slot such that a plane in which the shortest dimensional value lies intersects the slot side surfaces.
