In recent years, thanks to the gradual improvement of materials, people’s increasing understanding of hydraulics and in-depth research on vibration theory, coupled with new understanding of the cutting tooth technology and lithological matching issues, polycrystalline diamond compacts ( Polycrystalline diamond compact disc technology and polycrystalline diamond compact bit technology have been rapidly developed. The improvement and improvement of powder metallurgy technology has improved the quality of the carcass drill bit; advanced surface hardening technology and unique geometric design have improved the working performance of steel drill bit, and advanced designs such as reducing the number of blades and increasing the blade height have emerged. Through the understanding and understanding of the issue that “drillability is not completely dependent on the hardness of rock”, there is a great leap in technology; breakthroughs in vibration analysis improve the durability and penetration rate of bit; the cutting structure and The polycrystalline diamond compact cutting teeth are matched with the specific drilling environment and lithology, which reduces the drilling cost. The new design of the polycrystalline diamond compact drill bit optimizes the drilling hydraulics and solves the problem of bit mud packs. 


The point of view of the new polycrystalline diamond compact cutting teeth that the durability of polycrystalline diamond compact drill bits depends on the size of the cutting teeth and the number of blades is no longer valid. The person concerned believes that the durability of polycrystalline diamond compact drill bit depends on the type of cutting teeth rather than the number of cutting teeth. Improvements in material quality and cutting tooth design have eliminated the limitation on the thickness of diamond chips for high-quality cutting teeth. In recent years, various new types of polycrystalline diamond compact chips have been introduced abroad. TecMaLx cutting teeth are equipped with two layers of diamond chips. 


The impact resistance and wear resistance of the cutting teeth are optimized on the first layer of diamond chips, while increasing the diamond volume on the second layer of diamond chips can extend the life of the bit. The lithology-specific SonicMax cutting teeth were developed for a new generation of drill bits. The new cutter's gold A-stone thickness is twice that of traditional high-quality cutters. The cleverly designed curved joints plus advanced sintering processes reduce the stress level at the diamond chip location and tungsten carbide and diamond joints. The new drill bit has an increased diamond volume and improved durability.
