Diamond composite sheet (PDC) is a special superhard material synthesized by synthetic diamond and hard alloy at one time under high temperature and high pressure. It not only has the advantages of high diamond hardness and wear resistance, but also has the characteristics of hard alloy, such as strong impact and large cutting edge. All over the country's coal fields, oil drilling, water conservancy and hydropower, railway, highway, tunnel construction and other industries.

Diamond composite sheet (PDC) is a special superhard material synthesized by synthetic diamond and hard alloy at one time under high temperature and high pressure. It not only has the advantages of high diamond hardness and wear resistance, but also has the characteristics of hard alloy, such as strong impact and large cutting edge. All over the country's coal fields, oil drilling, water conservancy and hydropower, railway, highway, tunnel construction and other industries.
Diamond PDC drill bit body is made of high quality steel (42CrMo) forging molding, through the vacuum automatic heat treatment equipment to increase the mechanical properties of the treatment.
The common type uses domestic high-quality composite sheets as blades, and the two-wing PDC anchor drill bit (standard type) is suitable for rock formation of grade 8, and the drilling life is common under the same rock formation conditions.alloy drill bit10-30 times, the efficiency is increased by at least 60%, no grinding is required, the labor intensity of workers is greatly reduced, and working hours are saved.
The key raw material of the two-wing PDC anchor drill bit (reinforced type) knife wing is produced by GE Company of the United States, its diamond content is 1.5 times that of ordinary drill bit, the wear resistance is excellent, the efficiency is significantly improved, the comprehensive cost is reduced, and it is suitable for the medium-hard rock formation below grade 12.
High-strength diamond bit blade wing adopts the newly developed ball diamond blade, which is characterized by fast drilling speed and strong impact resistance. When the drill bit is drilling, the lip is used for scraping the normal uniform formation rock, and the protruding part can inhibit the instantaneous large-scale footage when the drill bit encounters a gap during the drilling process, greatly reducing the accidental damage of the drill bit and improving the drilling level to deal with complex rock formations.
