High Air Pressure DTH Hammer

High-pressure down-the-hole impactor is a drilling device designed for high-pressure environments. It uses high-pressure compressed air (usually more than 2.5 MPa) to drive the piston to move at high speed. It is suitable for complex working conditions such as deep holes and hard rocks. Compared with ordinary down-the-hole impactors, it can work under higher pressure, provide stronger impact force and more efficient slag removal capabilities.

Hard rock drilling

Used for hard rock blasting holes in mining.

Mineral Exploration Drilling

Complex Geological Conditions

Suitable for drilling operations in complex geological conditions such as broken zones and faults.

Competitive Advantage

Efficient Drilling

High air pressure delivers stronger impact energy for faster penetration. Rapid slag removal keeps the hole clean, reduces sticking risk, and improves overall drilling efficiency.

Vibration icon

High Drilling Quality

Helps create straighter, smoother holes with less deviation. Stable operation improves drilling accuracy and overall hole quality in complex working conditions.

Durability icon

Strong Durability

Made from high-strength materials to withstand high air pressure and harsh environments. The durable structure extends service life and helps reduce maintenance and downtime.

Compatibility icon

Strong Adaptability

Performs well in deep holes, hard rock, and fractured formations. Suitable for mining, oil, gas, geothermal, and other demanding drilling applications.

save money

Better Economic Value

Higher efficiency shortens project cycles and lowers labor costs. Long service life reduces replacement frequency and helps cut long-term operating expenses.
