Frequently Asked Questions

Q: Which rock strata are most suitable for the 120mm Concave Coreless PDC Bit?

This bit is specifically designed for Grade 1 to 7 soft to medium-hard strata, including soil layers, loose rock, weathering layers, shale, marble, and medium-hard limestone.

Q: Can the connection threads be customized for my specific drill rig?

Yes, we offer full customization for connections. Common threads include 42, 50, 60, 73, 76, and 89, but we can manufacture any specific thread according to your requirements.

Q: What makes the "Coreless" design advantageous for drilling?

The coreless design typically allows for better debris removal and reduces the risk of clogging, which enhances the Rate of Penetration (ROP) and overall efficiency.

Q: How does the forged body improve the performance of the PDC bit?

The forged body provides significantly higher structural integrity and impact resistance compared to cast bodies, preventing premature failure in challenging geological conditions.

Q: Is this bit suitable for oil and gas field exploration?

Absolutely. While the concave coreless bit is versatile, we provide specific high-quality standards for oil field composite bits to meet the most stringent international requirements.

Q: What are the available diameter options for this product series?

We offer a wide range of diameters including 46, 55, 60, 65, 75, 91, 113, 120, 133, 153, 171, 200, 220, 250, 280, 300, and 325mm.
