Cutter element for rock removal applications

A cutter element for rock removal comprises a free standing PCD body (801, 1801) comprising one or more physical volumes (1702, 1703), the PCD material being invariant in terms of the diamond and metal network compositional ratio and metal elemental composition such that each physical volume does no...

More Information
Summary:A cutter element for rock removal comprises a free standing PCD body (801, 1801) comprising one or more physical volumes (1702, 1703), the PCD material being invariant in terms of the diamond and metal network compositional ratio and metal elemental composition such that each physical volume does not differ to any other physical volume with respect to diamond and metal network compositional ratio and metal elemental composition. The PCD body has a functional working volume (803) forming in use the region which comes into contact with the rock. A functional support volume (804) extant in use and having a proximal free surface extends from the functional working volume. The PCD body has an aspect ratio such that the ratio of the length (ae) of the longest edge of the circumscribing rectangular parallelepiped of the overall PCD body to the largest width (ad) of the smallest rectangular face from which the functional working volume extends of the circumscribing rectangular parallelepiped, is greater than or equal to 1.0.
