Abstract: Cutting elements of this invention include an ultra hard body joined with a metallic substrate. The body includes an uppermost layer comprising a plurality of bonded ultra hard crystals and interstitial regions, and that form a body working surface. The uppermost layer includes a thermally stable outer region that is substantially free of a catalyst material. The body includes an intermediate layer joined to the uppermost layer, comprising a plurality of bonded ultra hard crystals, and having a wear resistance less than that of the uppermost layer remaining region. The intermediate material can include a catalyst and other materials. The ultra hard crystals can be diamond, and the volume fraction of crystals in the uppermost layer can be greater than that in the intermediate layer. The body may additionally include a lowermost PCD layer interposed between and attached to the intermediate layer and the substrate.
