Frequently Asked Questions
What rock formations are these PDC bits best suited for?
They are designed for soft to medium-hard formations with a Protodyakonov hardness coefficient (F) up to 12.
Can the cutter size and blade number be customized?
Yes, cutter sizes (typically 13mm-25mm) and the number of blades can be customized based on your specific geological strata requirements.
What is the advantage of the parabolic crown profile?
The parabolic profile provides an optimized balance of force, resulting in high stability, excellent steerability, and a faster rate of penetration (ROP).
How do you ensure the durability of the bit body?
The bit body is manufactured from high-strength alloy steel with a hardness range of HRC 38-42, ensuring superior wear and impact resistance.
Is there deviation control during drilling?
Yes, our bits are engineered to maintain high precision, with deviation control effectively managed at ≤0.5° per 10 meters.
What type of packaging is used for international shipping?
Products are typically packed in high-quality wooden cases or steel boxes to ensure maximum protection during transit.
