PDC drag bit by using a polycrystalline diamond compact cutter, has high hardness and wear resistance, the drag bit blade between the body and the welding process, welding after the completion of the whole cutting, welding technology on compact, can according to customer request custom styles, because the blade between the body and the welding process, so the overall strength is better than the steel body and tire body bit, Mainly used for water Wells or mines, relatively soft formation style and blade can be customized, relatively speaking the price is also more advantageous.

The PDC bit is a kind of cutting bit with fins commonly used in the upper soft formation of oil drilling. It has two wings, three wings and four wings. The three wing PDC bit is commonly used. A drill breaks rock by scraping and shearing. The required weight on bit is very low, resulting in fast ROP and long life. The cost of drilling is greatly reduced.
