High Air Pressure DTH Bits are specialized drilling tools used in the mining, construction, and oil and gas industries for drilling boreholes or blast holes into hard rock or other challenging geological formations. These bits are designed to work with DTH drilling rigs, which use compressed air to drive the drilling process.
Working principle:
LEANOMS

Here's how High Air Pressure DTH Bits work:
Drilling Rig: A DTH drilling rig consists of a compressor that generates high-pressure air, a drill string (drill pipe and hammer), and the DTH bit.
Compressed Air: The compressed air is sent down the drill string to the DTH bit, where it is released through nozzles located around the bit's face.
Impact and Rotation: The high-pressure air creates a powerful hammering effect inside the bit. This hammering action, along with the rotation of the drill string, helps the DTH bit to break and crush the rock or formation in its path.
Cutting Structure: High Air Pressure DTH Bits have a specific cutting structure on the face, which can vary depending on the type of rock or material being drilled. This cutting structure may include tungsten carbide buttons, which are durable and can withstand the high-impact forces involved in DTH drilling.
Drilled Hole: As the DTH bit continues to hammer and rotate, it creates a hole in the ground or rock. The cuttings are forced to the surface through the annular space between the drill string and the newly formed hole.
High Air Pressure DTH Bits are preferred for drilling in hard and abrasive formations because they provide efficient penetration rates and maintain hole straightness. The high-pressure air not only aids in breaking rock but also helps remove the cuttings from the hole, preventing clogging and allowing for faster drilling progress. These bits come in various sizes and designs to accommodate different drilling requirements.
