    This is particularly design for shallow holes, as is often the case in water well drilling, geothermal wells and for shallow micro-piling work.

    Odex is ideal for short holes in consolidated overburden.

    Eccentric Drilling Tools with casing tube step-by-step:

    1 - When drilling, the PGZ(Eccentric Drilling Tools) reamer swings out and drills a hole wide enough for the casing tube to slide down behind the reamer.

    2 - When required depth is reached, the dill is reversed and the reamer swings in, allowing the bit to pass through the casing.

    3 - Casing tube is pulled out directly or fixed at the bottom of the hole by means of cement grout or other ragglutinant.

    4 - Drilling continues to the desired depth using conventional DTH equipment.
