PDC (Polycrystalline Diamond Compact) Cutter

Name: PDC (Polycrystalline Diamond Compact) Cutter
Brand: Henan E-Grind Abrasives Co., Ltd.

E-Grind produces high-quality Polycrystalline diamond composite(PDC) and polycrystalline diamond compact cutters.

Polycrystalline diamond composite(PDC) sheet is made of diamond particles and cemented carbide matrix sintered at 60,000 atmospheres, high temperature and high pressure above 1500 ℃, and has the high hardness of diamond and the high toughness of cemented carbide. The diamond composite sheet has extremely high wear resistance, impact resistance and good thermal stability, and is specially used for oil drilling bits and can also be used for other rock or mining drilling operations.

Diamond PDC structure


	Diamond Table The uniform micron size distribution, make PDC high bonding force and high density.Various particle sizes can meet customer needs for wear resistance and impact resistance demand.
	Interface We have various interface desgin to ensure optimal combination,
	Substrate E-Grind using 13% and 16% Co carbide substrate as standard specificaiton. Ensure the carbide substrate brazed strength to the drill bit body.

Shaped PDC Diamond

Shaped PDC

Diamond-reinforced composite cutter are formed by sintering diamond particles and cemented carbide matrix at high temperature and pressure, which not only has the high wear resistance of diamond, but also has the high strength of cemented carbide. The products are widely used in roller cone bits, down-the-hole drill bits, picks, crushing machinery and other fields, and are the best substitute for cemented carbide cutter.
The diamond-reinforced composite cutter adopts the transition layer technology between the diamond layer and the cemented carbide layer, which has outstanding impact resistance and ultra-high wear resistance, making it widely used in high-end PDC bits, such as shock-absorbing cutter, Center cutter, gauge cutter, etc.
