Product Description

6-1/2 6 Blade PDC Rock Bit Water Drill Bit Coal Mining Drilling Machine


PDC bits are far less expensive than natural diamond bits, but are only suitable for soft to
edium hard formations. 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.
