PDC for oil drilling bits series
The Description of PDC drilling bits:
PDC for oil drilling bits series is produced by using the higher degree of diamond power and tungsten carbide substrate through adopting advanced international technology.
Features of PDC drilling bits:
Microstructure with complete C-C bond combination is characterized between the grains of the diamond in polycrystalline diamond layer, which allows the high strength, hardness and wearing properity of diamond layer.
We adopt many types of claw structure of the interface between diamond layer and tungsten carbide substrate, and use the special technological lateconditions in order to effectively reduce residual sterss of PDC while make the interface combination firmer and more symmetrical.so applied to oil drill bits, PDC displays sstisfying thermal stability, higher impact resistance and excellent performance.
