China Prodrill High air pressure 3-12 inches down the hole dth hammer

 

General Introduction:

We manufacture DTH Hammers in different sizes ranging from 3 to 12. These hammers are made corresponding to Drilling Bits to carry out prevalent objectives. These hammers are used in various down the hole operations like bench Drilling. These are valve less hammers with optimized air cycle frequency. These are heavy duty hammers that well at greater depths demanding less air usage, delivering minimum performance loss. We offer IR hammer, DHD3.5, DHD340a, DHD360, DHD380, COP and QL  SD NUMA hammer. The optimum range of hole size for blast drilling with DTH is 90mm to 254mm, smaller blast holes are generally drilled using top hammer, and larger holes generally use rotary machines. Our hammer like COP and QL are known fort heir reliability and longevity.

 

Description

 

Our DTH hammer and bits are compatible with CIR, DHD, QL,SD,Mission, etc. series of Atlas and Sandvik etc.

Product Application

1. Non-Blocking:Our S-series DTH hammers are proved to ensure extremely low rate of blocking during it works.

2. High Efficiency:The well drilling equipment carries with larger power of impact frequency and torque, thus ensuring faster penetration. Compared with others, the efficiency can be improved 10%.
3. Longer Service Life:All surfaces of the DTH hammer and bits are treated by anti-friction and intensified technology. When used in deep-hole drilling works, it can reach at 5000 meters or more.
4. Excellent Cleaning Effect: This DTH tool has large air output, which specially designed for water well users and enables it to flush out cuttings in deep hole drilling works.
Scope of application:
Mining, quarry, road building, well hole drilling, blasting, landslide prevention, dam reinforement, anchoring, geothermal, hydrology, etc.
