PDC composite drill bit

      PDC composite drill bit is a widely used drilling tool in the fields of oil and gas drilling, as well as geological exploration. PDC composite drill bits transmit torque and axial pressure to the drill bit through the drill rod during the drilling process. When the drill bit rotates, the PDC composite cutting edge comes into contact with the rock surface, utilizing its high hardness and sharp cutting edge to cut and break the rock. At the same time, drilling fluid is sprayed onto the surface of the drill bit through the water hole, cooling and cleaning the drill bit, and carrying the cut rock debris to the surface. With the continuous drilling of the drill bit, the PDC composite piece gradually wears out, but due to its high wear resistance, it can maintain good cutting performance for a long time, thereby improving drilling efficiency
