mining drilling tools,
Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.
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 also has the followingadvantages:
1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of DTH hammer designed according to newest rock drilling theory.
2. Smooth performance and long service life of 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.
All our products, which passed ISO9001 quality management system, are widely used in open pit mining,tunneling, quarrying, transportation construction,engineering, earth-rock excavation, water wells, pile foundation, and civil engineering project etc. We are one of the companies which have the most complete product lines, the most abundant species and the most widely used products in drilling industry.

1. Using the latest rock drilling theory,optimizing the inside structure and the size of the air distrbution,to make the DTH hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.
2. For such projects as the drill bit break,retrieving very difficult,we specially designed a safe and reliable anti-shedding device for the bit.
3. The check valve can be replaced to replaced to the one with bigger air controlling hole to provide more efficient cutting discharge.
4. The top sub and the drive chuck have special thread,which can achieve an easier disassemble.
1. Fast drilling speed and low air consumption due to the special inner structure.
2. Smooth performance and long service due to high quality alloy steel materials and advanced processing.
