Product Description
MRING90 Overburden Casing Drilling System with Ring Bit for Underground Coal Mining
Product Description
Rock drilling tools factory KINGDRILLING professionally produce Ring wing bit concentric drilling systems by down the hole hammer which are designed to drill and case a hole simultaneously through unstable ground conditions. A driver bit and a ring are assembled to a complete RING system bit which is suitable for 114-1067mm diameter casing tube.
Advantages of Overburden Casing Drilling System:
Enhanced Operational Efficiency: OBCD eliminates the need for multiple trips downhole, reducing overall drilling time and enhancing operational efficiency.
Improved Casing Integrity: By installing casing simultaneously with drilling, OBCD ensures better casing integrity and reduces the risk of hole collapse or formation damage.
Cost Savings: The streamlined nature of OBCD results in significant cost savings by reducing drilling time, equipment requirements, and operational complexities.
Increased Safety: With reduced operational risks and improved hole stability, OBCD enhances safety for both personnel and equipment.
Versatility: OBCD can be adapted to various drilling scenarios, making it a versatile solution for different geological conditions.
