Abstract
A cutter element for rock removal comprises a free standing PCD body () comprising two or more physical volumes () within the boundary of the PCD body, wherein adjacent physical volumes differ in one or more of diamond and metal network compositional ratio, metal elemental composition and diamond grain size distribution, a functional working volume () distal to the PCD body, the functional working volume forming in use a region which comes into contact with the rock. A functional support volume () extant in use and having a proximal free surface extends from the functional working volume. The PCD body has a shape having 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, and one or more of the physical volumes forms at least part of one or other or both of the functional working volume and the functional support volume.
