DIAMOND PDC BIT AND DIAMOND CORE BIT
 
1.THE DEscriptION  FOR DIAMOND PDC BITS
 PDC bit,PDC bits,diamond bit,PDC core bit,6 blades PDC bit
1.Blades and Capacious Flume
Symmetrical parabola crown profile,asymmetrical bit blades ,the cutters are distributed as the curve and the gauge is designed spiral so that  the stability of the bit is encouraged.Besides that the edge of gauge is enhanced by extra cutters. The flow roomage is optimal designed so that the mud and rock granule can be clear easily in drilling.
2.High wear resistance cutters.High performance PDC cutters optimal designed highly increased the efficiency of drilling.
3.Oppose-circumnutation designed.The load on bit is balanced,and the journal libration is decreased as well as the stabilization of directional drilling is enhanced.
4.This type of bits are suitable for  medium to hard formation.
4.BIT CHARACTER

These types of bit have some common features, as follows:
1. Force balanced, resist impact to the blade during high-speed drilling, to make bit work stable.
2. Plus wear knot section, reduce collision in the high-speed rotational vibration.
3. Patented matrix formulation, extended bit life.
4. Optimal hydraulic design, easy to move out the drill cuttings and cooling.
5. Equipped with back reaming teeth.
6. The cutter is high performance to increase the ability of anti-impact and anti-abrasive

A Polycrystalline Diamond Compact is composed 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 malleability and the capacity to weld of the whole composite.
When applied to petroleum and geology drilling bits, as well as machine tooling, PDC will show excellent comprehensive properties and the will also produce good economic performance
