Product Description

Company Introduction:
We are able to manufacture, export and supply our clients excellent quality DTH & RC drilling tools, like DTH & RC hammers,bits,overburden casing system ,tricone bits and etc. These tools are meticulously manufactured with utmost perfection by utilizing superior quality raw materials and efficient machinery. 

Product Introduction:
In the projects of drilling,drillers often meet with problems due to the loose land formation.These may cause troubles such as difficulty in drilling down,collapse of holes,damage of drilling tools,etc.To solve the problems,the best way is to use (ODEX)Overburden Drilling System which can prevent holes and drilling tools from damage,and support the holes by casing tubes.

Working Principle:
1. When drilling starts, the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly
2. When the required depth is reached, rotation is reversed carefully, whereupon the reamer swings in , allowing the drill bit assembly to be pulled up through the casing.
3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hole by means of cement grout or some other sealing agent.
4. Drilling continues to the desired depth in the bedrock using a conventional drilling.
