PDC Mining Core Drill Bit for Geological Exploration and Rock Core Sampling

PDC Mining Core Drill Bit is designed for geological exploration, mineral exploration and rock core sampling in soft to medium sedimentary formations.

The bit uses high-quality PDC/PCD cutting elements to provide fast penetration, strong wear resistance and stable core drilling performance. Different cutter sizes, quantities and core bit standards can be selected according to drilling system and formation conditions. Available in BQ, NQ, HQ, PQ and customized wireline core drilling sizes, with PDC cutter options such as 1304 and 1308.

Fast penetration and stable core drilling performance

Six design advantages behind the PDC Mining Core Drill Bit.

Focused on geological, mineral and mining exploration

The PDC Mining Core Drill Bit is focused on core drilling applications requiring continuous rock core sampling. It is not intended for the very broad range of applications sometimes listed for all PDC bits.

PDC Core Bit vs Impregnated Diamond Core Bit

PDC and impregnated diamond core bits are suited to different formations and drilling priorities. The correct choice depends on formation hardness, abrasiveness, drilling interval length and required penetration rate.

NQ reference size and product parameters

NQ reference dimensions are shown below. Other sizes and customized dimensions are available on request.

Wireline core bit sizes

Common wireline core bit sizes are listed below. Actual supply depends on project requirement — please confirm the specific size before ordering.

Cutter size and quantity matched to formation

Final cutter quantity should be selected according to bit diameter, formation hardness, abrasiveness and required penetration rate.

How to select the right PDC mining core bit

For an accurate recommendation, please provide the following information. If you do not know the specific model, send us your current core barrel or drill bit photo and our team can help identify the correct size.

Customized PDC mining core bit solutions

Every core drilling project is different. We can customize the core bit according to your core barrel system, formation and drilling requirements.

From core bit size and cutter configuration to crown structure and waterway design, core bits can be configured according to specific project conditions. Our engineering team works with your technical data to recommend the most suitable cutter layout and core bit structure. — Core Bit Size — Outside Diameter — Inside Diameter — PDC Cutter Size — Cutter Quantity — Cutter Layout — Crown Structure — Waterway Design — Connection — OEM Marking — Packaging
