Abstract (en)
A polycrystalline diamond cutter and method of manufacturing a polycrystalline diamond cutter is disclosed. The method of manufacture comprising assembling a first substrate component (30), a second substrate component (32) and diamond crystals (34) into a desired configuration. The assembly is subjected to high temperature and high pressure conditions to cause the diamond crystals to bond to one another and to the first and second substrate components. The method forms a cutter having a single body of polycrystalline diamond bonded to the substrate components. <IMAGE>
