Odex Casing System

-ODEX tool is a three-piece assembly including pilot bit, reamer and guide device

-When drilling begins, the ODEX reamer swings out and drills a hole wide enough for the casing tube to slide down behind the reamer

-when required depth is reached, reverse rotating direction, the reamer will swing in which allows the ODEX assembly to be passed through and pulled out of the casing

l permanent symmetric drilling system

-when drilling begins, central bit drive ring bit down to the hole bottom, meanwhile, the casing shoe and casing tube is pushed and pulled down

-when arriving bedrock, reversely rotate the drill engine and central bit is pulled out from the hole

-by using cement grout or other agglutinant, casing tube can be fixed at the bottom of the hole or casing tube can be pulled out directly

-change to normal drill tools for continuous drilling until the required depth is reached
