DTH Hammer accounts for more than 70% of the entire market due to its strong wear resistance and long footage. DTH Hammer is favored by many users. Drilling into different types of rocks and choosing different quality diamond heads can achieve good results. The carcass is the core component of a PDC bit. What are the measures to improve the performance of the carcass?

1. Strengthen the drill carcass to improve the carcass performance. The performance can be improved by strengthening and selecting the carcass and improving the impregnated alloy formula. The strengthening of the drill bit matrix can be achieved by adding a small amount of nickel and drill to the carcass powder which is helpful for dispersion strengthening and improving the wettability of the matrix powder of the carcass.

2. Research on the tooth-fixing technology of PDC bits is also an important method to improve performance. The drill bit matrix is ​​a sintered body of cast tungsten carbide powder as the skeleton and impregnated alloy. The composite sheet is a composite superhard material synthesized by a cemented carbide matrix and a thin layer of polycrystalline diamond under high temperature and high pressure. The tooth-fixing technology can solve these two problems. Composite material brazing connection problem. This process of diamond drill manufacturers can make the drill bit more durable and not easily damaged.

3. The hardness of the drill matrix can be adjusted by the tap density of the skeleton powder. The greater the tap density, the higher the hardness of the matrix. Using different proportions and particle size of the skeleton powder is an effective way to improve the density of the drill bit matrix.

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