8 inch HDD single roller core bit / roller core cutter for the hdd rock reamer / HDD roller bit

1) PDC bit, also known as polycrystalline di amond composite bit, has been widely used in the oil and gas drilling industry and directional well construction. It has the advantages of long working life and 1ow downhole accident rate.  2) Size: 6 -121/4 inches 3) The material of the drill body is divided into: steel body and carcass. The steel body is cheap to build and the carcass is resistant to friction. 4) Drill blade: 4.5.6. 7.8 knife  5) Diameter of composite sheet: 13mm. 16mm . 19mm
