Element Six designs and manufactures a range of standard and customised polycrystalline diamond cutters (also known as polycrystalline diamond compacts or PDC) for use in oil & gas drill bits. Our comprehensive range of standard and special products offers the widest possible drilling solutions to meet the challenging requirements of oil & gas exploration and production.
Polycrystalline diamond cutters (PDC) comprise a polycrystalline diamond (PCD) top layer integrally sintered onto a tungsten carbide substrate using a high-pressure, high-temperature process. This layer combination allows consistently high drilling performance to be maintained. The polycrystalline diamond layer offers controlled wear and the retention of a sharp cutting edge. The tungsten carbide substrate provides a strong and tough support for the polycrystalline diamond layer while facilitating attachment to the drill bit body.
