The document describes different types of polycrystalline diamond compact (PDC) cutters produced by a company, including round, spherical, and irregular shapes. It provides specifications for multiple series of round PDC cutters (SSI, SSII, SSIII) that vary in diameter, thickness, and diamond layer thickness. The document also gives specifications for spherical and sample irregular shaped (quadrate, triangle) PDC cutters that the company manufactures.

1. Polycrystalline Diamond Compact (PDC) of our company is sintered with diamond
and WC under ultrahigh pressure and temperature. It integrates the advantages of
diamond and WC, with both extremely high wear resistance and excellent shock
strength. Be suitable for manufacturing all kinds of drilling tools, such as oil,
geological and engineering drilling bits .
By shape, Our PDC cutter includes three types:
1.Normal round shape
2.Sphere shape
3.Irregular shape
For round shape, We have 3 series which are listed as below:
SSI Series Polycrystalline Diamond Compact adopts flat tine junction plane. The
thickness of diamond layer
is about 0.8~1.2mm. It is
mainly used in stone
processing and hole (blind
hole) can be punched
according to customers'
requirements.

SSIII series Polycrystalline Diamond Compact adopts new net-slotted junction plane,
which better removes internal stress of polycrystalline diamond compact; meanwhile
the thickness of diamond layer is increased to 1.8~2.5mm and makes wear resistance
much higher.

For Sphere Shape, we make globular tooth shape and blunt
conical-ended shape now.
Globular tooth shape cutters Compared with conventional-type Polycrystalline
Diamond Compact, it has more excellent shock-resistance toughness (ballistic work is
equal to that of hard alloy) and it can be applied to percussion drilling, medium and
small drill bit, oil roller bit, down- the-hole
drill bit and geothermal drilling etc.

We can cut any shape according to the customers’ requirements for both round
shape and sphere shape, below is a photo of cut round shape and a photo of a
drilling bits which use this type of cutter.
For irregular shape PDC cutter, we usually cut the PDC according to customers’

5. requirements, below is our heterotypic shape and triangle shape that we produce at
present. Our irregular shape PDC cutter is usually using for processing various of
stone, for example, marble, limestone, etc.
Heterotypic Compact
Our company can manufacture irregular
Polycrystalline Diamond Compact according to
customers' detained requirement. At present, mass
production is applied in rectangular compact and
triangle compact. Nonstandard product-i.e.those not
confirming to any listed specification, may be
supplied on request.
