Key Features:

. Available for casing sizes from 114mm (4 1/2") to 273mm (10¾") diameter Simple two-part design for better transfer of energy to Bit face
. Optimal drilling performance in unstable ground conditions
. The Eccentric Bit can be easily and quickly removed for replacement or refurbishment
. "open and closed" locking arrangement inside the bit holder so nothing can prevent the Eccentric Bit from closing
. The ODS Bit has a positive pilot design which helps guide the Eccentric Bit and produce a straighter hole


Application Range:

It is suitable for drilling water wells, geothermal wells, short mirco piles, 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.
