4 Inch DHD340 DTH Hammer

The common DTH Hammer series are as follows:

COP series: COP series DTH Hammer is a product of Sweden Epiroc (formerly Atlas Copco). This series is characterized by a simple internal structure, easy maintenance, high impact capacity and penetration speed. DTH Hammer of COP series has COP 32, COP 34, COP 44, COP 54, and other models, which can be applied to different rock hardness and drilling diameter.

 

SD series: SD series DTH Hammer is a product of the British Sandvik company. This series is characterized by the ability to achieve high-efficiency drilling in various rock conditions, with advantages such as long life and low maintenance costs. The DTH Hammer of the SD series has SD 5, SD 6, SD 8, SD 12 and other models, which are suitable for various rock hardness and drilling diameters.

 

QL series: QL series DTH Hammer is a product of Swedish Epiroc (formerly Atlas Copco). It has high impact capability and drilling speed and is suitable for hard rock and hard formations. The DTH Hammer of QL series has QL 30, QL 40, QL 50, QL 60 and other models, which are suitable for different rock hardness and drilling diameters.

 

M series: The M series DTH Hammer is a kind of DTH Hammer produced by domestic manufacturers in China. It has the advantages of low price and stable performance. It is suitable for some rocks and soil layers with medium hardness. The DTH Hammer of M series has M3, M4, M5 and other models, which can be applied to different rock hardness and drilling diameters.

 

In general, the differences between different series of DTH Hammers lie in the differences in design, performance, the scope of application, maintenance, etc. The selection of a suitable DTH Hammer needs to consider factors such as specific engineering requirements and rock geological conditions.

 

DHD series drilling tools are high-quality drilling tools, suitable for drilling in various geological conditions. DHD drilling tools adopt advanced design and manufacturing processes, which can provide excellent drilling performance and service life.

 

In, including DHD3.5, DHD340, DHD350, DHD360, and other models, can meet different drilling needs. Among them, DHD3.5 is suitable for shallow drilling, DHD340 is suitable for medium and deep drilling, and DHD350 and DHD360 are suitable for deep drilling.

 

4-inch DHD340 DTH Hammer has good wear resistance and corrosion resistance and can maintain high-efficiency drilling capabilities under harsh geological conditions. The structural design of the drill bit and drill pipe can also reduce vibration and noise, and improve the stability and comfort of drilling.

 

4 Inch DHD340 DTH Hammer is compatible with many different types of drilling rigs, including surface drilling rigs, underground drilling rigs horizontal directional drilling rigs, etc., and can flexibly respond to different drilling needs. At the same time, DHD drilling tools are also easy to maintain and replace, which can reduce drilling interruption and maintenance costs.

 

In general, DHD series drilling tools are high-performance and high-reliability drilling tools, which are widely used in drilling operations in mines, tunnels, subways, construction, and water conservancy projects.

 

The rock drilling bit in DTH hammers is an extension of the shank that the rock drill piston strikes directly. Little energy is lost because the piston and drill bit are in direct contact The 4-inch DHD340 DTH Hammer benefits from a nearly constant penetration rate regardless of the size of the hole.

• Drilling diameters of a small to medium size;

• Operates in the low-pressure range and can drill short to medium-length holes.
