This high air pressure DTH hammer work without footvalve is designed and developed by our own, which is the one of the most advanced DTH hammer in the world.
1. 10 years manufacturing experience
2. Certificate: ISO9001:2015
3. Material: Carbide
It has the following advantages:
1. Avoid the problem happens on foot valve such as Fracture, expansion and contraction.
2. Lower air comsumption and higher impact frequency, 15%-30% higher drilling efficiency than the bit with foot valve.
3. Simple structure and less spare parts, which means easier and cheaper maintenance.
4. Heat-hardened spare parts, makes longer serving life and less problem.
5. Thread connection for top sub and drive chuck makes easiser disassembly.
