Rock Drilling Eccentric Overburden Casing System Odex Drill
DTH Button Bit
Description
ODEX/Eccentric equipment enables you to drill and case deep holes
simultaneouslyin all types of formation, even those with large
boulders.
The method is based on a pilot bit and eccentric reamer, which
together drill a hole slightly larger than the external diameter of
the casing tube. This enables the casing tube to follow the drill
bit down the hole.
When using ODEX, part of the impact energy is diverted to the
casing tube via a shoulder on the guide device, which in turn
impacts a special casing shoe at the lower end of the casing.
Quality warranty:
Our products are made of high quality steel and all spares parts
