A PCD cutting element (2010) having a table of superhard material (2022) bonded to a substrate (2024). The superhard material has a first end working surface and an intermediate peripheral working surface (2028) adjacent the substrate. A cavity (2002, 2004, 2006) is formed in the substrate in an area immediately adjacent the peripheral working surface to expose a second end working surface. One particularly advantageous use of this new PCD cutting element is as cutting elements for earth boring drill bits.

L'invention concerne un outil de coupe PCD (2010) muni d'une plaque de matériau extra-dur (2022) liée à un substrat (2024). Le matériau extra-dur comporte une première surface d'usinage d'extrémité et une surface d'usinage périphérique intermédiaire (2028) adjacente au substrat. Une cavité (2002, 2004, 2006) est formée dans le substrat dans une zone immédiatement adjacente à la surface d'usinage périphérique pour exposer une seconde surface d'usinage d'extrémité. Ce nouvel outil de coupe PCD peut être utilisé de façon particulièrement avantageuse en tant qu'outil de coupe pour trépans de forage.
