The size of Kingdream PDC bits ranges from 3 1/2” to 26”, eight functional product series are formed and product types include PDC bit, hybrid bit and the bit with other features.
 
For the Hybrid Bit Technology:
Hybrid Rock-fracture: Fully merge the double advantages between rock-fracture through impact crushing by a roller cone bit and the rock-fracture through scraping by a PDC bit to improve drilling efficiency in complicated formation significantly; 
Technological Advantage: Rolling cones reduce the operating torque of the bit to make the tool face more stable; the cutting efficiency of PDC cutters is higher and the service life is longer through preliminary breakage by roller cones; the formation applicability is wider through hybrid rock-fracture technology.
