Rock Drilling Tool ODEX Symmetric Casing Drilling Systems DTH Drill Bits
ODEX is an excellent option when unconsolidated formations are too dense or cobbly for Auger Drilling. ODEX is a down-hole air hammer system that is designed to advance casing during drilling. Once a desired depth is reached they eccentric bit can be retrieved leaving the casing in place for sampling or installations.
Features
Hardening treatment of the part's surface
with longer operating life and excellent anti - wear properties.
Structural optimization
Strengthen the structural strength, easy to operate
Superior performance
Stable and reliable performance, high drilling speed
When the bore-hole is complete, the casing is retrieved to be used again.
Pros
Rapid removal of cuttings;
No use of drilling mud;
High penetration rate, especially in resistant rock formation (e.g. basalt);
Easy soil and groundwater sampling during drilling;
Possible to measure yield estimate at selected depth in the formation;
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.
