Name of Product

With professional manufacturing experience in DTH hammer production, our factory can supply you with high pressure and medium to low pressure DTH hammers. It strictly matches with API standard and other Chinese industry standards. It is durable for being produced with advanced craftwork and good material.

It has the following advantages:

1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of HD series DTH hammer designed according to newest rock drilling theory.

2. Smooth performance and long service life of HD series DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.

3. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner structure of hammer.

4. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.

5. Interchangeable with DTH bit and drill pipe.

1.Compatible with the bits of COP/DHD/QL/SD series.

2.Simple piston structure increases its lifetime.

3.Adopt valveless air distribution.Simple structure makes it easy for dis-assembly.

4.With faster drilling speed and less power consumption.

5.When required to increase deslagging,holes can be added on reverse valve.

6.Adopt fine alloy steel and apply hardening treatment on the spare parts,which prolongs DTH hammer lifetime and lifts reliability

High Air Pressure DTH Hammer(with foot valve)

It is a kind of valueless high air pressure DTH hammer with foot valve.

Advantages:

1.Valveless air distribution, more reliable;

2.Piston with simple but compact design, long service life

3.More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.

4.Fewer internal parts, simple structure, longer life, less failure and easier to maintain, with the all heat treated parts;

High Air Pressure DTH Hammer(without food valve)

It's a king of high air pressure DTH hammer without footvalve,our newest design. it's also one of the most advanced DTH hammer in the world.

It has the followingadvantages:

1.Out of the trouble of foot valve fracture and expansion and contraction;

2.Lower energy consumption and higher impact frequency. The drilling speed is 15-30% higher than the one with foot valve;

3.Simple structure, reliable parts, long life, easy and cheap maintenance;

4.Lower air and oil consumption, the oil consumption is about 10% lower than the one with foot valve.

According to your request, the top sub can be made into two spanners, an air controlling hole can be drilled on the check valve to provide more efficient cuttings discharge.

DTH Bit

DTH bit is also our main product. After mang years search, we have rich experience in development and manufacturing high quality products, which adopted high-quality raw materials, advanced technology and passed through strictly inspection.
