Overburden | Eccentric-Symmetrix | Concentric Odex Drilling Tools With Casing Tube

Always Odex DTH drilling tools include Overburden-Eccentric drill tools with casing tube & Symmetrix-Concentric DTH drilling tools.

The Odex system utilizes an eccentric under reamer to cut a drilled hole ahead of the bottom of the casing. The casing is then simultaneously advanced by a percussive force applied to either the top or bottom of the casing. As the hole is advanced, the drill cuttings are normally removed by air and travel up the inside of the casing in the annular space between the casing ID and the drill rod OD. The Odex method is highly effective in overburden soils where boulders or gravel layers are present, or when layers of rock must be penetrated. This method also subjects surficial and localized soils to some vibration.

We have sizes 4", 5", 6" and 8" Odex systems available.

Odex drilling hole diameter:

Overburden-Eccentric: 114-324mm.

Symmetrix-Concentric: 114-610mm.

Currently Odex drilling is available from 3" to 8" DTH hammers.
