Product Description

6-3/4 5 Blade Oil Well Drill Bit Water Drill Bit PDC Cutter Drilling Machine


PDC bits are less expensive than natural diamond bits. After the PDC bit was successfully manufactured

and used in the early 1970s, it has developed rapidly. It can be used with lower drilling pressure and higher rotational speed, with high drill bit footage and low unit footage cost. Some oilfields in China use

diamond polycrystalline composite sheets to be welded on the scraper, and good results have also been obtained.
