A POLYCRYSTALLINE SUPER HARD CONSTRUCTION AND A METHOD OF MAKING SAME
A polycrystalline superhard construction comprises a body (20, 51, 52) of polycrystalline diamond material, a working surface (34), a first region (51) substantially free of a solvent/catalysing material, the first region extending a depth (Y) from the working surface into the body along a plane substantially perpendicular to the plane along which the working surface extends, and a second region (52) remote from the working surface that includes solvent/catalysing material in a plurality of interstitial regions. A substrate (30) is attached to the body along an interface (24) with the second region. A chamfer extends between the working surface and a peripheral side surface of the body. The depth of the first region tapers towards the working surface at the intersection of the first region with the peripheral side surface such that the depth (Y′) of the first region at the peripheral side surface is less than the depth of the majority of the first region.
