TDD,born for drilling. 

TDD have been focusing on DTH drilling for 16 years. We are specialized in manufacturing various DTH drilling hammers、matched drilling bits、drilling rigs and drilling pipes for water wells、mines and oil industries.

TDD has been promoting productivity in drilling industry, SPM ensure the safety and stability of drilling engineering, and provide professional, efficient and reliable whole drilling solutions. 

TDD have made tremendous development at the basic of high-quality, low price, good service since its establishment. All friends both at home and abroad are warmly welcomed to come here to establish and develop business relationship with us. 

TDD 8 inch High Pressure DTH Air Drill Hammer S80 is very popular in international well drilling field. 

TDD 8” DTH Drill Hammer S80 drill holes from 203mm to 254mm. Matched drilling bits:S80-203、S80-216、S80-219、S80-235、S80-241、S80-254.  

Advantages of TDD high air pressure DTH hammers:

1. Non-Blocking：Our S-series Down the hole 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.

We also supply other 5”、6”、10”、12” High Pressure DTH Air Drill Hammers and various matched drill bits, We offer TDD high air pressure DTH hammer size from 5″ to 12″(Φ125mm-Φ275mm), TDD DTH hammers perform good in drilling well of diameter from 140mm to 508mm, especially excellent in deep hole well drilling works. Different designing makes TDD DTH drill hammers are suitable for various well drilling conditions.
