1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

- Mining In mineral exploration and extraction, DTH drilling provides fast and efficient drilling of blast holes, contributing to improved overall productivity in mines.

The submersible drilling rig, available in both internal combustion and electric models, is a device for drilling holes in rocks. The characteristics of drill drilling is outstanding, according to different characteristics can be divided into many varieties, different varieties of drill drilling scope is not the same, facing the classification of drill drilling, the way is briefly introduced as follows:

Additionally, the tools and technologies used on Mars will have to be adapted. For example, engines that rely on combustion would be less efficient in Mars’ thin atmosphere, requiring alternative propulsion methods. Moreover, the presence of carbon dioxide could be harnessed for in-situ resource utilization, converting CO2 into oxygen for breathing and fuel.

Ongoing missions, including rovers and landers, are equipped with advanced scientific instruments to explore the Martian surface and subsurface. Understanding the effects of Martian low pressure is crucial in assessing the planet's past and present habitability, as well as planning for future explorations.

4. Manufacturing In manufacturing, spiral drill bits are frequently employed in creating holes for assembly fixtures and machinery setups, providing both function and precision.

Moreover, the advancements in drilling technologies and techniques have made it possible to achieve highly efficient perforation results. Digital technology, computer modeling, and simulation are utilized to anticipate how the geological formations will respond to drilling activities. By utilizing advanced analytics based on parameters such as 3 32, engineers can devise optimized perforation strategies that align with both production goals and regulatory standards for environmental protection.
