Product Description

Sollroc HSD8A Down The Hole Drilling Tools Drilling Hammer 

Our Products:

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.

Products Description

Sollroc high pressure DTH hammer has the advantages of fast action, large impact power, less gas consumption, long life and so on. Widely used in geotechnical engineering to create all kinds of hard, hard, poor drillability of rock tenacity, its features are as follows:
1 the impactor design has strong blower system, high pressure gas can be all used for slag discharge; the wear jackets hardening tube can be a U-turn, so you can extend the period of replacement.
2 design of adjustable gas plug, according to rock hardness and abrasion resistance, can discharge gas drilling different adjustment, in order to achieve the best effect of slag, so as to achieve the highest efficiency;
3 simple structure, few parts, plus the use of wear-resistant parts, the impact of the working time longer;
4 before the joint using a multi thread and the outer cylinder connection, the impact of the removal of the drill bit easier.

The Characteristics of High Air Pressure DTH Hammer with foot Valve.

1. Valveless air distribution.More Reliable
2. Simple design of the piston,long life
3. More efficient energy transfer,fasting drilling speed,lower air consumption and lower oil consumption
4. Fewer internal parts,simple structure,longer life,less failure and easier to maintain because all the parts are heat treated
5. Easy to disassemble because the top sub,the drive chuck and the external cylinder are connected by multi-step thread

The Characteristics of High Air Pressure DTH Hammer without foot Valve.

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

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
