Surface set diamond core bits are mainly used in geological drilling and other fields, and they have the following characteristics:
1. High drilling efficiency
Hardness advantage: Natural diamond is the hardest substance in nature, with a Mohs hardness of 10. The diamond particles embedded on the surface protrude from the surface of the drill bit body. During the drilling process, these hard diamond particles can directly cut into the rock, resulting in a high efficiency in breaking the rock. Compared with some other traditional drilling tools, such as hard alloy drill bits, natural surface mounted diamond drill bits can drill faster in hard rock formations.
Good wear resistance: Diamond itself has good wear resistance, and it can maintain sharp cutting edges for a long time during continuous drilling operations. This ensures that the cutting performance of the drill bit remains good even after a long working time and drilling distance, thereby reducing the frequency of frequent drill bit replacement and improving the overall efficiency of drilling.
2. Good drilling quality
High dimensional accuracy: Natural surface mounted diamond drill bits have high diamond particle embedding accuracy during the manufacturing process, which can ensure the dimensional accuracy of the drill bit. During the drilling process, this high-precision drill bit can drill holes with correct dimensions and good roundness. For some projects that require high precision in drilling size, such as certain measurement boreholes in petroleum exploration and small core sampling boreholes in scientific research, natural surface mounted diamond drill bits can well meet the requirements.
Smooth hole wall: Due to the high hardness and sharp cutting edge of diamond, it can effectively cut rocks during drilling, making the drilled hole wall relatively smooth. Smooth borehole walls can reduce the increase in drilling resistance and wear of drilling tools caused by rough borehole walls during the drilling process. At the same time, for situations where subsequent operations need to be carried out inside the borehole (such as installing casing, lowering instruments, etc.), a smooth borehole wall is also more conducive to the smooth progress of these operations.
3. Wide adaptability range
Suitable for multiple rock types: Natural surface mounted diamond drill bits can adapt to various rock types ranging from soft to hard rocks. For soft rocks, although the drilling difficulty is relatively low, the high wear resistance and high precision characteristics of natural surface mounted diamond drill bits can still play an advantage in drilling high-quality boreholes. For hard rocks such as granite and basalt, the diamond particles of the drill bit can effectively break the rock and complete the drilling task with their hardness advantage.
Adaptability in different drilling environments: Natural diamond drill bits can perform well in different drilling environments, such as dry and wet drilling conditions. In a wet drilling environment, the drill bit can be better cooled and lubricated by flushing fluid, extending its service life; In a dry drilling environment, as long as the drilling parameters are reasonably controlled, the drill bit can still effectively drill, but more attention needs to be paid to the heat dissipation of the drill bit.
4. Long service life
Durability of Diamond: Natural diamond has good chemical stability and hardly reacts with any chemical substances at room temperature. During the drilling process, even when encountering corrosive geological environments such as groundwater containing certain chemicals, diamond particles are not easily corroded. Moreover, due to its high hardness and good wear resistance, the diamond particles of natural surface mounted diamond drill bits can maintain their cutting performance for a long time under normal drilling conditions, thereby extending the service life of the drill bit.
Reasonable inlay structure: The inlay structure of surface mounted diamond drill bits enables diamond particles to be firmly fixed on the surface of the drill bit body. This structural design can prevent premature detachment of diamond particles during drilling, further ensuring the service life of the drill bit. In practical applications, through reasonable design and manufacturing processes, the drill bit can maintain good performance during long-term drilling operations.
