PDC inserts, PDC oil drill bit cutters ,PDC cutter for drill bits

PDC cutters

Specialisted in producing varies kinds of PDC cutters/ PCD cutters/ PDC cutter insert in China for many years. Including PDC rock cutter for geology exploring, PDC rock cutter for oil & gas well drilling bits, PDC for coal field mining drilling bits series, PDC blanks for cutting tools series, PCBN blanks for cutting tools.

The polycrystalline diamond compact (PDC) cutter is compact of a polycrystalline diamond layer and a tungsten carbide substrate. The polycrystalline diamond layer possesses extremely high hardness and abrasion resistance, whereas the tungsten carbide substrate would greatly improve the toughness and weldability of the whole compact.

The features of PDC cutters:
(1)long life-Employing new sinter techniques firms the bonding of diamond particles. The abrasion resistance has a vast increase, with 2-3mm of the diamond layer, this assure the diamond compact cutter has a longer life.
(2)Higher impact resistance-The beveled interface of diamond layer and tungsten carbide, reduces residual stress of PDC diamond compact cutter, and increase impact resistance.
(3)Thermal stability-the resist temperature reaches 800°C,which makes reliable quality and better performance when PDC used in the drilling bits.

Oli drilling bits PDC Cutter

Features of PDC cutter

1. The PDC cutter has high abrasive resistance. High quality materials are sintered to form the diamond layer which is of rigid framework structure. The PDC features compact structure and good abrasive resistance.
2. The PDC cutter features good impact resistance. The PDC uses tungsten carbide material which has good impact resistance and the diamond layer can guarantee the toughness of the impact resistance.
3. The PDC cutter has strong binding force. The junction plane of the diamond layer and the tungsten carbide layer uses a corrugated tooth design. The binding force can be increased and the bad impact of the plane residual stress on the PDC performance can be avoided.
4. The PDC cutter has good self sharpening performance. The good organization microstructure of the diamond makes the diamond particle remain sharp all times.
5. The PDC cutter features good thermal conductivity. Its highest bearing temperature can reach 700°C.

Application of PDC cutter

The PDC cutter is used for drilling bits for oil, gas and coal.

Material of PDC cutter
The PDC cutter uses diamond powder and tungsten carbide.
