151mm PDC Single Tube Core Bit

151mm PDC Single Tube Core Bit – Thin Wall Design for Fast Drilling in Soft and Weathered Formations

The 151mm PDC Single Tube Core Bit is a specialized drilling tool designed for geological exploration, geotechnical investigation, water well drilling, and other core drilling applications. Featuring a thin-wall construction and high-performance PDC cutters, this core bit is engineered to deliver fast penetration rates and efficient drilling performance in soft to medium-hard formations.

This model is equipped with 1004 PDC cutters as standard, providing an effective cutting structure for rapid rock penetration. For different geological conditions and drilling requirements, 0904 PDC cutters are also available as an alternative option.

The thin-wall design helps reduce unnecessary drilling resistance and improves drilling efficiency, making it suitable for projects where high penetration speed and productive drilling operations are important.

PDC Cutter Options and Drilling Performance

Our 151mm PDC single tube core bit can be manufactured with either 1004 or 0904 PDC cutters according to customer requirements.

The selected PDC cutter configuration provides efficient cutting performance in formations such as mudstone, muddy sandstone, frozen soil, permafrost, red sandstone, and weathered rock.

With its optimized cutting structure, this thin-wall PDC core bit is a practical solution for drilling contractors looking to improve drilling speed, reduce operating time, and maintain consistent drilling performance.

Suitable Geological Formations and Applications

This PDC single tube core bit is particularly suitable for:

• Mudstone and soft sedimentary formations

• Muddy sandstone and sandy mudstone

• Frozen soil and permafrost formations

• Red sandstone and weakly cemented sandstone

• Weathered rock and decomposed rock layers

• Soft to medium-soft geological formations

Recommended Engineering Applications

1. Geological Exploration Projects: Used for geological investigation, rock sampling, and shallow core drilling in suitable formations.

2. Geotechnical Investigation: Suitable for soil and rock investigation before construction, infrastructure development, and foundation engineering.

3. Mining Exploration: Used in mineral exploration drilling and geological assessment where the formations are suitable for PDC cutting.

4. Water Well Drilling: Applicable to water well drilling projects involving soft rock, weathered formations, and sedimentary layers.

5. Permafrost Drilling Projects: Designed for drilling operations in frozen soil and permafrost geological environments.

6. Engineering Survey Drilling: Suitable for site investigation, geological surveying, and engineering exploration projects.
