Reaming Dia. 168mm Eccentric Overburden Casing Drilling Bit for Hole Drilling

Description:

1. When starting 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 if cement grout or some other sealing agent.

4.Drilling continues to the desired depth in the bedrock using a conventional drill string.
