Polycrystalline diamond cutter
blanks
(PDC） |
Polycrystalline Diamond Compact (PDC) of Supreme 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. Polycrystalline Diamond Compact standard specification of Supreme Company is round and other special specifications can be made according to customers’
requirements. Be suitable for manufacturing all kinds of drilling tools, such as oil, geological and engineering drilling bits Polycrystalline Diamond Compact (PDC) of Supreme Company has following three series:
Supreme PDC cutter includes:
1.
Round shape
2.
Sphere shape
3.
Irregular shape which are used to cut various of stone,
for examples, marble, granite, etc.
For Round shape, we have 3
series which are listed as below:
■ SSI Series
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.

Typical Order Code:
For
Sphere PDC cutter, we make globular
tooth shape and Blunt conical-ended shape now.
Globular tooth shape insert, blunt conical-ended shape insert
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.
