Product Description

PRODRILL ODEX165
Prodrill produces the ODEX Eccentric Overburden Drilling System, starting with the ODEX90 to suit 114mm O. D. Casings. This two-piece system comprises the shank bit holder and the eccentric pilot bit that is secured in the bit holder by a double interlocking pin. This is easily removed to allow for bit are sharpening or replacement. Prodrill ODEX overburden drilling systems are widely used in a variety of applications from well drilling and mining to rock anchoring and site investigation.

Application Range:
It is suitable for drilling water wells, geothermal wells, short mircopiles, medium mini-type grouting hole of building, dam and harbour project.
1. When drilling starts, the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly
2. When the required depth is reached, rotation is reversed carefully, whereupon the reamer swings in, allowing the drill bit assembly to be pulled up through the casing.
3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hole by means of cement grout or some other sealing agent.
4. Drilling continues to the desired depth in the bedrock using a conventional drilling.
