Introduction and applicable rock formations of diamond composite drill bitsThe PDC piece in diamond composite drill bits is a special wear-resistant and superhard material synthesized by combining artificial diamond and cemented carbide under relatively high temperature conditions. Diamond composite drill bits not only have the advantages of super hardness and wear resistance of diamond, but also have the strong impact resistance and large blade of cemented carbide. The blade of the drill bit made of diamond composite piece greatly improves the working efficiency of the drill bit, which is an ideal choice for drilling medium-hard rock formations and hard rock formations.Diamond composite drill bits are made of high-quality steel forging and are subjected to vacuum full-automatic heat treatment equipment to increase mechanical properties. Applicable rock formations are also divided according to the hardness of the drill bit. Generally, diamond drill bits are divided into ordinary and enhanced types:Ordinary type: using domestic high-quality composite pieces as blades, suitable for rock formations with a hardness of 3-10.Super strong type: using blades produced by GE of the United States, suitable for rock formations with a hardness of 6-12.
