PCD tool processing diamond milling cutter
Description of Diamond coated inserts PDC inserts
1.PDC cutters are sintered with selected diamond powder and
tingsten carbide compact under high temperature and ultra high
2. The PDC cutters have high hardness, high abrasion resistance and
high impact resistance.
3. PDC bttons bits can be widely used for oil and gas well drill
bits, geological drill and mining drill bits. The PDC cutters can
also be used as cutting tools with diamond for cutting, griding and
Application of PDC cutters:
PDC cutters are widely used for petroleum and oil field PDC bit,
geological PDC exploration bits, gas exploration bits, PDC coal
mining drill bits. PDC is mainly applicable for PDC drilling bit
for drilling into soft and intermediate-hardness stratum.
Advantages of PDC cutters:
1.New cutting surfaces will appear during the course of abrasion,
which keeps effective cutting rocks
2.high strength, high hardness and high wearing property of diamond
layer as well as good self-sharpening
3.PDC drilling bit made of such PDC will break up rocks depending
on shearing action when it works, which is more effective than
crushing of rocks by roller cone bit or plowing and grinding of
rocks by diamond impregnated bit
4.The serrate structure combination between polycrystalline diamond
layer and hard alloy substrate allows more fixed combination
between the two layers and more impact resistance of the whole PDC.
Sort by bit material
The mole PDC bit
The matrix diamond composite (PDC) bit is a cutting bit which is
welded to the drill head via brazing.The matrix bit is sintered
with tungsten-carbide powder, brazed on the tungsten carbide matrix
with synthetic polycrystalline diamond composite sheet, and
preserved with natural diamond.
Steel PDC bit
Steel PDC bit is machined with nickel, chromium and molybdenum
alloys.After heat treatment, drill holes were drilled into the bit
body, and the strong synthetic polycrystalline diamond composite
was pressed into (tightly matched) the bit body.
According to applicable industry classification
The composite bit for geological exploration
The composite drill bit, mainly used in geological survey and
exploration, is suitable for soft to medium hard rock layers. Now
some manufacturers have developed a new composite sheet which can
be applied to the rock layers with a tenth degree of hardness.
The utility model relates to a composite chip drill
It is mainly used for coal seam drilling and mining.Generally
speaking, rock strata of coal field are relatively soft, and
composite bit is widely used, such as anchor bit and three-wing
Composite bit for petroleum exploration
Mainly used in oil and gas field drill bit.At present, the
composite drill bit used in oil field is the cost and requirement
of all composite drill bits.It's sort of the aristocracy of the
composite drill bit.

PDC Rock Cutter for Oil Well Drilling Bits
How PDC cutters are made ?
Cutters are made using a combination of high heat and high
pressure. Man made diamonds can be grown in 5-10 minutes. Because
of this diamond content, a fixed cutter bit may also be known as a
diamond drill bit.
High heat plus pressure creates a PDC (polycrystalline diamond
Cutters are made from a carbide substrate and diamond grit. High
heat of around 2800 degrees and high pressure of approximately
1,000,000 psi forms the compact. A cobalt alloy is also present and
acts as a catalyst to the sintering process. The cobalt helps bond
the carbide and diamond.
During the cooling process, the tungsten carbide shrinks at a rate
of 2.5 times faster than the diamond. Controlling this stress, as
with most aspects of drill bit design, is called Intellectual
Property, and manufacturers rarely, if ever, share their secrets.
PDC Cutter for oil Industry
The diamond composite is composed of a layer of polycrystalline
diamond and a hard alloy matrix.
Oil pdc cutter is will micro diamond powder and cemented carbide
substrate and super high pressure high temperature (about 60000
atmospheres, 1400 - a - 1500 ℃) under the condition of sintering,
Suitable for drilling in various layers of king kong composite chip
bit (PDC bit).
The diamond grains in the polycrystalline diamond layer have
complete d-d bond bonding, which makes the diamond layer have high
strength, high hardness and high abrasion resistance, as well as
The rock is broken by shearing action, which is more effective than
the crushing rock of the cone bit or the plough cutting and
grinding rock of the diamond impregnated bit.
The combination of polycrystalline diamond layer and hard alloy
matrix is in the form of tooth structure, which makes the bond
between the two layers more solid and ensures the drill bit to be
more resistant to impact.
