1. Helical Design The most striking feature of spiral drill bits is their helical shape, which improves the efficiency of cutting and drilling. This design allows for smoother penetration into materials, reducing the likelihood of the bit becoming stuck or overheating.

Key Features of the CFM 185 Air Compressor

- Construction For foundations, pilings, and site preparation, DTH techniques enable precise hole placement and stability in challenging geological conditions.

Submarine hammer drilling sees extensive applications in several sectors

Conclusion

2. Pump Material The selected materials should offer resistance to erosion and corrosion, especially when handling abrasive slurries. Common materials include rubber-lined components, stainless steel, and high-chrome alloys.

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.
