8 Inch Eccentric Casing ODEX Drilling System SOLLROC Rock Drilling Tool
Sollroc's Symmetric Casing Drilling Eccentric Drilling Casing System is designed to drill holes of many sizes, ranging from 115mm to 324mm (4 to 12 inch), at any angle (including horizontal), to any depth (beyond 100 meters) through unconsolidated formations simultaneously with casing. The internal flushing grooves together with the built-in casing shoes gives a good seal to the button of the drilling hole, and thus minimizing the disruption of the surrounding of the drill hole. It makes the casing follow easy and the equipment and operation simple, and is recommended to a multitude of applications, such as micro-piling, underpinning, anchoring, marine work and horizontal drilling etc.
1.Rapid removal of cuttings; High penetration rate, especially in resistant rock formation;
2.Easy soil and groundwater sampling during drilling;
3.Possible to measure yield estimate at selected depth in the formation;
4.Advantageous in unconsolidated formations with a high risk of caving.
Eccentric Overburden Drilling System Consist of Guide device, Casing shoe, Reamer, Pilot bit, Guide sleeve and Locking kits

Operating principle:Products Photos:
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 hoe by means of cement grout or some other sealing agent.
4. Drilling continues to the desired depth in the bedrock using a conventional drilling tools.
