Product Description

DHD340/SD4/QL4 Shank Overburden Casing Drilling System Bit for Mineral Exploration

Product Description

Eccentric bit is made up of a pair of chain emmbedded to guide apparatus, and ensure the bit is not contacting and damaging the retaining ring when it is rotating. When rotated clockwise, eccentric part will be expanded to bring the casing tube into hole. After completing, eccentric bit will be closed while rotated anticlockwise, and it can be lifted up by the drilling machine. This casing drilling bit is especially suitable for diameter 114-273mm.

Advantages of Overburden Casing Drilling System:

The Overburden Casing Drilling system offers a multitude of advantages over traditional drilling methods, making it a preferred choice for many drilling applications. Some of the key advantages include:

1. Improved Efficiency: By combining casing advancement and drilling into a single operation, the OCD system significantly reduces drilling time and overall project duration. This efficiency translates to cost savings and increased productivity.

2. Enhanced Borehole Stability: The simultaneous casing installation and drilling process in the OCD system help maintain borehole stability, even in challenging geological conditions. This results in reduced risks of borehole collapse and wellbore instability.

3. Reduced Environmental Impact: The OCD system minimizes the environmental footprint of drilling operations by reducing the volume of cuttings generated and mitigating fluid loss into the surrounding formations. This eco-friendly approach aligns with sustainable drilling practices.

4. Versatility: The Overburden Casing Drilling system is versatile and can be utilized in a wide range of applications, including geotechnical drilling, water well construction, environmental remediation, and mineral exploration. Its adaptability makes it a valuable tool across diverse industries.

5. Cost-Effectiveness: By streamlining the drilling process and eliminating the need for separate casing and drilling operations, the OCD system offers cost savings in terms of equipment, labor, and operational expenses. This cost-effectiveness makes it an attractive option for various projects.
