Description

Eccentric Drilling Tools with Casing Tube

Eccentric is the most economical solutions because its ingenious reaming wing the bit is retrievable can be used at the next hole. 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.
