SEM test report:

PDC Cutters (Polycrystalline Diamond Compact) are consisting of a polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high pressure and ultra-high temperature. They are produced with carefully chosen high-quality industrial diamond and tungsten carbide materials as well as advanced synthesizing technology. 

Designed for oil/gas drilling and mining bits.

Features:

a). High abrasion resistance

b). High impact resistance

c). Reasonable Inter-beded formations

d). High thermal stability

Advantages of pdc:

1)Diamond powder grit is uniform,don't contain impurities, 

 high purity,Round crystal and High compressive strength  

2) Unique technical process：The binder is evenly distributed in the connect   of pcd working layer and tungsten carbide   

3)Professional package.

4Long lifespan and stable performance

5) High impact resistance

6) Excellent after-sales service

The PDC Cutter is widely used for oil &gas exploration, geology,waterwell,coal mining etc.As diamond layer’s high abrasion resistance,it also used for stone cutting and industrial cutting tools.

Quality control workshop:

1.- Impact resistant testing :  

When using , drilling requires high impact resistance ,when finished a lot PDC , we will choose 5% sample for testing in impact resistance .

2.- Temperature resistant testing : 

When drilling , long time drilling will make its temperature higher , so PDC has to have an ability to face high temperature drilling .

3.- Working lifespan testing :

In order to guarantee our working life , we will choose some sample for testing in working life . Our testing way is drilling granite , granite hardness is higher than other geological .
