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.

of  applications from well drilling and mining to rock anchoring and site 
investigation.

medium mini-type grouting hole of building,dam and harbour project.

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.
