A method or process for making polycrystalline diamond or polycrystalline CBN cutting tools (Superabrasives), which have integral chip-breaking features is disclosed. This method involves pressing a die or other like rigid component against either the outer can cover or the diamond or CBN region directly. This invention provides economical manufacture of diamond chip-breaker tools, while avoiding unnecessary EDM EDG, grinding, or laser processes. This process forms the chip-breaker on the upper surface of the diamond region, during or prior to sintering. This invention permits a wide variety of chip-breaker or other diamond surface features, while minimizing cost and processing steps. Disclosed embodiments include: pressing through the can assembly; pressing within the assembly by introducing a rigid component in the can; and pressing two cans together with an intervening rigid component imposing the desired diamond surface features.

A cutting element, insert or compact, is provided for use with drills used in the drilling and boring of subterranean formations. This new insert, in its preferred embodiment, has a &ldquo;hoop&rdquo; region of polycrystalline diamond extending around the periphery of the compact to reduce the residual stresses inherent in thick diamond regions of cutters, thereby providing improved wear and durability characteristics because it avoids failures due to stresses, delaminations and fractures caused by the differences in thermal expansion coefficient between the diamond and the substrate during sintering. Moreover, this invention may provide multiple polycrystalline diamond edges as the PDC wears.
