Frequently Asked Questions
Q: What geological formations are best for this PDC bit?
This bit is optimized for Grade 1 to 7 soft to medium-hard strata, including soil layers, loose rock, weathering layers, shale, medium-hard limestone, and marble.
Q: Can the thread connection be customized for my specific rig?
Yes, we offer full customization for all kinds of threads, including common specifications like 42, 50, 60, 73, 76, and 89mm to ensure a perfect fit for your equipment.
Q: What is the difference between coreless and cored PDC bits?
Coreless bits are generally more cost-effective and offer higher drilling speeds in specific formations, making them ideal for exploration and coal field drilling.
Q: Is this bit suitable for oil and gas exploration?
Absolutely. Our PDC bits for oil exploration are manufactured to the highest quality standards to meet the rigorous demands of oil and gas field drilling.
Q: How does the forged body benefit the drilling process?
The forged body provides superior structural strength and impact resistance compared to cast bodies, significantly reducing the risk of failure in unstable rock layers.
Q: What other diameters are available for the concave coreless bit?
We provide a wide range of diameters, including 46, 55, 60, 65, 75, 91, 113, 133, 153, 171, 200, 220, 250, 280, 300, and 325mm.
