PDC product tooth tooth design techniques and fabric also achieved a major breakthrough

In addition to materials and manufacturing processes aspects of development other than, PDC products in the tooth's design techniques and cloth tooth aspects of also achieved a  polycrystalline diamond . Now, PDC products have been may be used for previously can not be applied of the regions, such as a more hard-, abrasive Xing the stronger and changeable  cutting tools . This kind into new areas in the expansion of, right diamond (fixed cutting teeth) the drill bit and roller cone drill bit the balance between the occurred had a great impact.
Initially, PDC drill bit can only be used for soft shale formations, the The reason is hard-'s  Abrasive grinding wheel  the drill bit. But due to emergence of new technologies as well as changes in the structure, at present PDC drill bit has been able to is used to drilled hard interlayer and a long Duan's hard rock stratigraphic it.
