Definitions

  • Figure 7 shows an arrangement where a leading cutting structure 29 has spaced rearwardly thereof, with respect to the width of a blade 30, a second cutting structure 31, the projecting portion of each cutting structure having partly embedded therein a thermally stable cutting element as indicated at 32 and 33 respectively.
  • the inner cutting structures 74 are of conventional form and each comprise a circular preform cutting element mounted on a stud located in a socket in the bit body.
  • Each cutting element may comprise a thin facing layer of polycrystalline diamond bonded to a backing layer of tungsten carbide, the rear surface of the backing layer being bonded, for example by brazing, to a suitably orientated surface on the stud.
  • each preform may comprise a circular unitary tablet of thermally stable polycrystalline diamond material bonded to the stud.
