PDC (Polycrystalline Diamond Cutters)

Polycrystalline diamond cutter

PDC cutter contains polycrystalline diamond layer and tungsten carbide backing. It features both the high shock resistance of tungsten carbide and the highest hardness & abrasion resistance of diamond.

Application: Oil & Gas and Mining.

Diamond Enhanced Cutter (Dome PDC Cutter)

Diamond enhanced cutter (DEC) is synthesized by diamond particle and tungsten carbide supporting layer at high pressure and high temperature. It is the best replacement to tungsten carbide insert.

It combines both the high wear resistance of diamond and high toughness of carbide.

Application: high-class PDC bits as the gauge, anti-vibration, or center cutters, percussion bits, cone bits, mining picks, PDC bits ...

E-Grind supplies Diamond Enhanced Cutter (Dome PDC cutter) with various shapes: spherical, conical, bullet-shaped, wedge… Our DEC has high impact resistance and wear resistance.

E-Grind provides full ranges of PDC specs. Three series are available:

EA-PD1

The Diamond section is with flat tine junction plane. The thickness of the 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.

Specification:

EA-PD2

Diamond-section is with slotted junction plane. The thickness of diamond layer is about 1.2~2.0mm.

EA-PD3

Diamond section is with 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.
