Product Description

8-5/8 6 Blades Diamond Drill Bit Water Well PDC Drills Drilling Machine


The polycrystalline diamond composite drill bit is a round shape of the composite chip, which is inserted and welded on a cylindrical cutting tool, and the cutting tool is inserted on the drill bit body to become a PDC drill bit. 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.
