Frequently Asked Questions

What materials are these core drill bits suitable for?
Our core drill bits are primarily made from high-grade Tungsten Carbide and industrial diamonds, making them ideal for geological drilling through various rock formations, including hard, medium, and soft strata.
Can I request customized specifications for my drilling project?
Yes, we offer customization services. Beyond the standard AQ, BQ, NQ, HQ, and PQ sizes, we can manufacture bits to meet specific diameter or length requirements according to your technical needs.
What is the quality standard for these products?
All our products are manufactured under strict ISO9001 quality management systems to ensure durability, precision, and high performance in demanding drilling environments.
What is the difference between the Q series and T series bits?
The Q series (Wireline) is designed for efficient deep-hole drilling where the core is retrieved through the drill string, while the T series is often used for conventional core drilling with specific wall thickness requirements.
What is your monthly production capacity for export?
We have a robust production capacity of approximately 50,000 pieces per month, allowing us to handle both small and large-scale global orders with standard export packaging.
Do you provide reaming shells to match these drill bits?
Yes, we provide matching reaming shells for all drill bit models (BTW, NTW, HTW, etc.) to ensure the hole diameter is maintained and the drill string is stabilized.
