Product Description

8-5/8 5 Blade Rock Drill Bit Water Well Drill Bit Drilling Machine


PDC drills are less expensive than natural diamond drills. After the successful manufacture and use of PDC drills in the early 1970s, development has grown rapidly. It can be used at lower drilling pressure and higher rotational speed, with higher bit footage and lower cost per footage. Some domestic oil fields use diamond polycrystalline composite sheets to weld on the scraper, and good results have also been obtained.
