Product Details
Under reaming systems are the most economical solutions for casing
drilling in normal ground conditions. This is particularly true for
shallow holes, as is often the case in water well drilling. We have
sizes 4", 5", 6" and 8" ODEX systems available.
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.
Currently Odex is available from 3" to 8" DTH hammers.
Odex 90 for 3" hammers;
Odex 115 for 3" and 4" hammers;
Odex 140 for 4" and 5" hammers;
Odex 165 for 5" and 6" hammers;
Odex 190 for 6" and 8" hammers;
Odex 240 for 8" hammers.
