Overburden drilling hole Diameter: ODEX-eccentric: 114-324mm                                                 

Symmetrix-concentric:  114-610mm


Features:

 

•     Pilot bit is well designed to offer good drilling efficiency.

•     Optimization design for each part reduces the probability of accident.

•     Strengthening quality of stable pole driller extends the drilling life and improve cost-4,performance ratio.

Drilling through this so-called overburden is often problematic, due to the tendency of the earth to cave in behind the drill bit.
 

This makes it difficult to retrieve the drill string after the hole has been drilled. In practice, the bore hole is often lost before a casing tube can be inserted to support it.
 

Other problems are caused by cavities or porous ground, which interfere with the circulation of the flushing medium and prevent the drill cuttings from being flushed out of the hole.
 

In places where overburden strata are mixed, or when their drillability is unknown, it is difficult for the driller to decide what tools to use in order to get the best overall results without risking the loss of equipment in the hole.
 

The best solution for dealing with such problems is to use ODEX equipment.
