  　　Diamond composite PDC Tapered Bit account for more than 70% of the entire market due to their strong wear resistance and footage length, and tire-type PDC drill bits are favored by many users. Drilling into different types of rocks and choosing different quality diamond heads can achieve better results. The carcass is the core component of a PDC bit. What are the measures taken by Tapered Bit manufacturers to improve the carcass performance?

  　　 1. The hardness of the drill skeleton can be adjusted by the vibration density of the skeleton powder. The greater the vibration density, the higher the hardness of the carcass. Using different proportions and particle sizes of the skeleton powder is an effective way to increase the density of the drill bit.

   

  　　2. Strengthen the drill bit carcass and improve the carcass performance. By strengthening and selecting the matrix and improving the impregnation alloy formula, the performance of the alloy can be improved. Adding a small amount of nickel and drill bits to the base powder can improve the wettability of the base powder.

   

  　　3. The research of PDC bit fixation technology is also an important means to improve the performance of the bit. The drill bit matrix is ​​a sintered body with cast tungsten carbide powder as the skeleton and impregnated alloy. The composite material is a composite superhard material synthesized by a cemented carbide matrix and a thin layer of polycrystalline diamond under high temperature and high pressure. Fixed tooth technology can solve the problem of brazing connection between two composite materials. This process makes the drill bit more durable and less susceptible to damage.

  In addition, we must pay attention to the diamond drill bit during our drilling and use: inject water first, then advance; open the hole first, then drive in; the pressure is uniform during the travel, and the speed should be reduced in case of hard rock, and the pressure should be reduced and the pressure should be moved forward at a uniform speed. Do not press and rush, it will cause serious damage to the composite sheet and carcass of the Drill pipe!
