Product Description

MRS Concentric Casing Drilling System with Reamer Bits for Stone Engraving Tools

Product Description

MRE Concentric under reaming drilling system is designed for unstable ground conditions. In the process of drilling, it could carry down the casing pipe to the hole to protect wall to achieve drilling work. At clockwise condition, eccentric part expanded to bring the casing tube into hole. After finished, eccentric bit closed anticlockwise and then can be lift up by the drilling machine. This type is especially suitable for diameter 114-273mm.

Features of Overburden Casing Drilling System:

1. Casing Advancement: The core feature of OCD is the simultaneous drilling and casing installation process. This method involves using a drill bit and a casing string, allowing for the casing to be advanced along with the drilling operation.

2. Reaming: The OCD system typically includes reaming tools that expand the hole diameter beyond the casing size, facilitating smoother casing insertion and minimizing the risk of getting stuck in unstable formations.

3. Reverse Circulation: Many OCD systems utilize reverse circulation techniques to remove cuttings from the borehole efficiently, preventing clogging and ensuring continuous drilling progress.

4. Versatile Design: Overburden Casing Drilling systems come in various designs and configurations to suit different ground conditions, casing sizes, and project requirements.

5. Compatibility: OCD systems can be used with various types of drilling rigs, offering flexibility in equipment selection based on project specifications.
