DTH drill bits are key components in DTH rock drilling projects. They are widely used in open-pit and underground mines, quarries, hydropower projects, water well drilling, mineral exploration, rock cable anchor hole drilling, geothermal drilling, subway engineering excavation, side pile support and other construction sites. They are also one of the main consumables. According to statistics, the cost of drill bits accounts for more than 20% of the cost of rock drilling.The polycrystalline diamond composite tooth DTH drill bit uses polycrystalline diamond composite teeth to replace the traditional carbide column tooth head. The polycrystalline diamond composite tooth is sintered by artificial diamond micropowder and carbide matrix (conical, spherical, wedge-shaped, parabolic, etc.) at high temperature and high pressure, and a layer of polycrystalline diamond layer is formed on the surface of the tooth head of the carbide matrix. Compared with the carbide column tooth head, the polycrystalline diamond composite tooth has excellent mechanical properties such as high strength and high wear resistance, and has been widely used in various fields such as drilling and mining.
