Frequently Asked Questions

Q: Why should I choose an 8-button (Q8) bit for hard rock?

A: The Q8 configuration distributes impact more evenly across 8 carbide tips, reducing wear per button and preventing premature failure in extremely hard rock like granite.

Q: Which taper degree is best for my rock drill?

A: We recommend 7-degree for lighter drills (Y24/Y26) and 11 or 12-degree for high-power air-leg drills (YT28/YT29A) to ensure a secure connection.

Q: What carbide grade is used in Q8 bits?

A: We use high-quality YK05/T6 Tungsten Carbide, which offers the optimal balance of hardness and toughness required for heavy mining roadway excavation.
