DTH hammers are used for blast hole drilling and water well drilling project.Working with DTH drilling pipe and DTH drill bit, mainly applied in Mining,Marble quarry or well drilling and other construction projects.

Down the hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powderto a down-the-hole bit to crush rocks.

Suitable choice of raw material, advanced processing technology and perfect quality warranty.
With hardened treatment, drilling life can be extended and then cost can be reduced.

Size range 1-2’’,3 ’’, 4’’, 5’’, 6’’, 8’’, 10’’, 12’’ etc.

Shank styles:









SD4, SD5, SD6, SD8,SD10,SD12;




Our DTH hammer are widely applied to open pit and underground mining to drill blasting holes, drainage holes, ventilation holes, center holes or blasting holes of raising boring, pipe holes and other deep holesin all various strength rocks, such as quarry exploitation, earthwork projects, water-well, constructionsand so on.

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.

Feature Advantage

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.

technology adapted

1. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner.

structure of hammer

1. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
2. Interchangeable with DTH bit and drill pipe.

The appearance of the picture is different from that of the actual product, and the actual product is the standard.
