What is the down the hole (DTH) hammer:


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. 


1. Based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.

2. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.

3. The  collection  tube  adopts  an  integrative  design  and  can  be  replaced  without  disassembling  the  hammer.  With  carburizing treatment, it has good abrasive resistance.

4. Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer

can drill holes of different sizes ensuring that the sample is not contaminated.

5. In difficult conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.

How the Down The Hole (DTH) Hammer function?


When percussion or hammer drilling the percussion mechanism is called a DTH or down the hole 

hammer. This drilling tool is located directly above the down hole hammer bit. The driller transfers

weight to the bit through the drill pipe as well as provides some rotation. Through the use of a 

compressor, the pressurized air is forced to the down hole hammer. As the drilled hole gets deeper 

the driller adds more drill pipe to the string. The piston strikes the impact zone of the hammer bit; 

hammers are always used as part of a casing advancement system and can be used in reverse 

circulation applications. DTH hammers are common when drilling blast holes and water wells. 


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 3’’, 3.5’’, 4’’, 5’’, 6’’, 8’’, 10’’, 12’’ etc.

Why buy our down the hole (DTH) hammer?


A rotation drill rig, air compressor and the DTH drill string are the essential unit for DTH drilling while the “DTH drill string” is always made up of DTH drill rods, DTH hammer and DTH bits. As one of key component, the DTH hammer acts as a role of converting the air pressure to the impact energy, simultaneously transferring impact energy and rotation force to DTH bits. All our hammers can be easily adapted to accept different types of bit shank as COP, BR, DHD, SD, QL, CIRand Mission by simply changing a few basic componets. Several models are available in Heavy-Duty format to suit particularly arduous and abrasive drilling conditions.



1. This middle and low pressure DTH hammer can effctively breaking rocks into rock powdder

and then remove them from the hole end, thus avoiding repeated breaking for rocks during hole-making process. Hence, it can effectively reduce abrasion to drill bits and helps improve hole making effciency.

2. The inner structure of the DTH hammer is designed based on the most current rock-drilling theories, which allows the drilling tool to have optimum energy transfer and offer powerful hammerming force. This ensures fast rock drilling speed and low air consumption.

3. Superior quality raw materials and latest production techniques make sure the down the hole hammer have reliable performance and long service life. Meanwhile, the tool is easy for mounting

and dismounting and is convenient for maintenance.
