Frequently Asked Questions

What are the primary advantages of your PDC Mining Drill Bits?

Our bits feature imported diamond composite cutters and precision heat treatment, providing exceptional wear resistance, high drilling efficiency, and a significantly longer service life compared to standard bits.

What type of rock formations are these bits suitable for?

They are designed for soft to medium-hard formations, typically with a rock hardness factor (F) of ≤ 10 or ≤ 12, depending on the specific model and crown design.

Can the bit specifications be customized for specific projects?

Yes, we offer customization for drill diameter, blade numbers, cutter types, and cutter sizes (from 13mm to 25mm) to perfectly match your strata conditions.

How is the drilling accuracy maintained?

We achieve a high level of deviation control (≤0.5°/10m) through optimized force-balanced designs and high-precision CNC manufacturing processes.

What materials are used for the drill bit body?

The bodies are manufactured from high-strength alloy steel with a surface hardness of HRC 38-42, ensuring maximum durability in abrasive mining environments.
