Abstract: A polycrystalline-diamond cutting clement (50) is disclosed for a drill bit of a downhole tool. The cutting element (50) includes a substrate (24) and a diamond table bonded to the substrate (24). The diamond table includes a diamond filler with at least one leached polycrystalline diamond segment (54) packed therein along at least one working surface thereof. The cutting element (50) may be formed by positioning the diamond table on the substrate (24) and bonding the diamond table onto the substrate (24) such that the polycrystalline diamond segment (54) is positioned along at least one working surface of the diamond table. A spark plasma sintering or double press operation may be used to bond the diamond table onto the substrate (24).
