We also produce air drilling tools and mud drilling tools, in addition to water well drilling rigs.
Our air drilling tools include DTH hammers and hammer heads. Air drilling is a technique that uses compressed air instead of water and mud circulation to cool drill bits, remove drill cuttings, and protect well wall. Inexhaustible air and easy preparation of gas-liquid mixture greatly facilitates the use of drilling rigs in dry, cold places and effectively reduces water costs.
Our mud drilling tools include tricone tooth bits, three wing bits, lock adapters, tricone bits, drilling rods, and drilling bits etc. They are carefully manufactured to ensure the stability of drilling rigs.
We are a Chinese water well drilling rig manufacturer. As a result of our commitment to product quality and services, we have been awarded the ISO9001: 2015 certificate, and our products have been CE certified.
