Eccentric casing System

Hardening treatment of the part’s surface:with longer operating life and excellent anti-wear properties. 

Structural optimization:Strengthen the structural strength, easy to operate

Superior performance:Stable and reliable performance, high drilling speed 

Working Principle of Drill:

1.When start drilling , 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.
