Frequently Asked Questions

What types of formations are these PDC bits suitable for?

These bits are designed for soft to medium-hard rock formations (F ≤ 10 to F ≤ 12), including coal, limestone, and various metal ores.

Can the drill bit specifications be customized?

Yes, we offer customizable specifications including diameter (ranging from 28mm to 350mm), blade numbers, and cutter types to meet specific mining needs.

What makes your PDC cutters different?

We use imported diamond composite materials combined with proprietary precision sintering and heat treatment to maximize wear and impact resistance.

How do you ensure drilling stability?

Our bits feature arc-shaped crowns and parabolic profiles based on force balance principles, which reduces oscillation and provides excellent steerability.

What is the hardness of the bit body?

The bit bodies are made of high-strength alloy steel with a hardness rating of HRC 38-42, ensuring long-term durability in abrasive environments.

Do you provide solutions for anchor drilling?

Yes, we have specialized PDC anchor bits (typically 28-32mm) that offer high hole quality and impact resistance without the need for regrinding.
