ODEX Components: pilot bits, reamer bits, guide device and casing shoe.
ODEX shank: CIR110 / CIR130
ODEX Usage: This is particular 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.
Economy: Eccentric is the most economical solutions because its ingenious reaming wing the bit is retrievable can be used at the next hole.
Working Principle:
When drilling, the reamer bit will rotate out to enlarge the hole which enough for the casing tube slide down behind the reamer. When reached required depth, the drill pipe will drill to the reverse direction and the reamer bit will retract, It is allowing the whole drilling system to pass through the casing.
Following is regular model:
| Model Size | Drill Bit Dia. | Hole Dia. | Casing O.D. | Casing Inner Dia. | Casing Shoe Inner Dia. |
| mm | mm | mm | mm | mm | mm |
| 146 | 129 | 163 | 146 | 130 | 120 |
| 108 | 95 | 125 | 108 | 96 | 86 |
| 108 | 95 | 125 | 108 | 96 | 86 |
