How does your "Self-Sharpening" design improve the penetration rate (ROP)?
Our optimized conical geometry and precision-fitted retainers allow the tooth to rotate freely 360 degrees within the holder during drilling. This constant rotation ensures uniform wear around the carbide tip, maintaining a sharp profile that maximizes penetration speed and reduces the mechanical load on your drilling rig.
How should I choose between different carbide shapes (e.g., cylindrical vs. ballistic)?
Selection depends on your geological report. For abrasive strata and soft rock, a larger cylindrical carbide offers better wear life. For very hard rock (100+ MPa), we recommend a ballistic or sharp conical tip to concentrate the crushing force and increase the advance rate.

How do I select the right pick for different geological conditions (e.g., hard coal vs. rock)?
Selection depends on the Rock Protodyakonov hardness (f-value) and abrasiveness. For soft coal, a sharper tip with a slimmer body increases the advance rate. For hard rock or coal with inclusions, we recommend a reinforced body and a larger, rounded carbide tip (ballistic shape) to withstand high impact and prevent tip fracturing.
Can you customize tools for my project?
Yes. We provide OEM/ODM services tailored to your specific geological reports (rock hardness/abrasiveness) to maximize tool life and efficiency.
