PDC core bit is manufactured by high-strength alloy steel bodies with premium PDC cutters.It serves as a core coring tool for geological exploration, core sampling, engineering investigation, and water well drilling. The advanced PDC cutter technology enables efficient penetration through various rock formations while maintaining sample integrity, making it the preferred choice for professionals requiring accurate subsurface analysis and reliable core recovery in diverse drilling environments.
Key Features
1. High-efficiency cutting and rapid drilling
The bit features spherical or flat PDC cutters with a high-hardness, strong wear-resistant diamond layer,Which can break rocks by cutting, greatly improving drilling efficiency and performing well in soft to medium hard rock formations.
2.Crown structure, high integrity of rock core
Multi nozzle crown design, smooth water flow, good cooling and slag removal effect; The internal pore structure of the rock core is reasonable, and the drilling process protects the rock core, reduces rock core fragmentation, and has a high rock core recovery rate.
3. Thickened, high-strength steel body; impact-resistant and durable
The body is forged with thickened alloy steel, which is impact resistant and not easily deformed;
4. Broad compatibility; easy assembly and disassembly
Features a standard male threaded connection, allowing for direct attachment to corresponding core barrel assemblies and compatibility with standard geological drilling rigs; outer diameter and PDC cutter can be customized as request.
Applicable Formations
Suitable for soft and medium hard rock layers: mudstone, shale, sandstone, limestone, weathered rock, etc
Main Applications
1: Geological and mineral exploration sampling
2: Water well drilling
3: Core sampling
4: Roadbed investigation
Operating Tips
1. Properly control drilling pressure and rotational speed during drilling to ensure smooth circulation of the flushing fluid, thereby cooling the bit and facilitating timely cuttings removal.
2. Reduce drilling pressure when encountering hard interlayers to prevent impact damage to the pdc cutters.
3. The drilling operation should be smooth and avoid damage to the threads due to collision.
