How to extend the service life of theDTH drill bit during deep-hole drilling

In deep-hole drilling applications, DTH Drill Bits not only reduce drilling costs but also improve drilling efficiency. DTH drill bits have high efficiency and long service life, with two structural forms: Medium and low wind pressure DTH bits and High wind pressure DTH bits, solving the problem of short lifespan of drill bits in strong and weak rock formations and achieving good results.

The difficulties encountered in traditional deep-hole drilling are long construction cycles and unstable borehole walls. With increasing drilling depth, the stability of the borehole decreases, making accidents inside the hole more likely. Frequent lifting and lowering of the drill string exacerbate damage to the drill rods. Therefore, according to the construction characteristics and conditions of deep-hole drilling, the longer the interval and return footage of lifting, the better. DTH drill bits are specialized tools for drilling rocks, so they play a significant role in deep-hole drilling applications.

HFD DTH drill bits have the characteristics of high efficiency and long service life, not only extending the working time of the drill bit at the bottom of the well but also reducing the number of lifting and lowering operations, achieving the goal of rapid sampling, meeting the requirements of deep-hole drilling, greatly shortening the construction period, and simultaneously advancing drilling technology to a new level.
