Civil construction tools

Feature:

On the basis of Eccentric Overburden Casing Systems, our factory created the Concentric Overburden Driling System A series, also called as the Five Sets, which haswon design research and development patent.

Compared to traditional overburden drilling systems, this product has following advantages:

1.multi-orientation simultaneously crush, so as to bear stress evenly and subsequently impact resistance.

2.dislaging easily

3.Drilling rod and casing could accelerate following up.

4.Operation, aseemble and unassembled the equipment is easy.

5.Multi-axis suspension is adopted, to avoid reamer from falling of.

Sizes available:

Type	Hole Diameter(mm)	Casing Size ( Wall Thickness * Outerdiameter)	DTH

Some application for the reaming drilling tools:

Civil engineering projects: anchoring, goating, pipe and cable laying. Blast holes without soil removal.

Mineral prospecting: pilot holes for diamond drilling,sampling cuttings,overburden thickness surveys,water table studies.

Water wells: casting form surface down to bedrock,casting all through unstable formations,exclusion of upper water layers which are frequenty polluted.
