Bit Dispkacers For PDC Drill Bit Manufacturing

                                  Bit Dispkacers For PDC Drill Bit Manufacturing

Drill bits known as either tri-cone or polycrystalline diamond compact (PDC) bits are used in
upstream drilling and evaluation operations. PDC drill bits feature polycrystalline diamond
compact cutters, as well as bodies made from steel or a matrix material (tungsten carbide).
CoorsTek displacers, or displacements, are used in the manufacturing process of the tungsten
carbide bit body to maintain the compact cutter pockets’ integrity during sintering.

Displacements are first fitted into a mold during the PDC bits manufacturing process, followed
by the tungsten carbide body and binder materials. The mold is placed in a furnace to sinter
the materials, and then it is cooled down and broken to remove the unfinished PDC bit.

After the body is sintered and the mold is discarded, the displacements need to be removed.
Removing the displacements leaves a pocket/cavity where the PDC compact cutter is positioned
and brazed into place.

Silicon carbide displacers provide a consistent pocket/cavity and are easily removed when the
body is cleaned after sintering.It is not unusual for a PDC bit to have 60+ displacements, so easily
cleaning the pockets/cavities represents considerable time and cost savings.

PDC drill bit displacers must be tough enough to withstand the drill bit manufacturing process, yet
they must be easily and cleanly removable from the drill bit pocket.Drill bit displacers are produced
from custom technical ceramic formulations to meet specific requirements of manufacturing and
usage.Using CoorsTek’s PDC bit displacers will improve efficiency and lower total cost of
operations.

We are large factory that produce all kinds of drill bits, such as PDC bits, tricone bits,hole opener
and so on.
