BQ/NQ/HQ/PQ Full-Specification Wireline Coring Diamond Core Bits
Product Overview
BQ, NQ, HQ, and PQ diamond core bits form a complete range of wireline coring tools engineered to deliver precise, high-integrity rock samples across diverse drilling scenarios. These bits are designed to match standard wireline coring systems, ensuring compatibility with most industry-leading rigs and core barrels while maintaining exceptional performance in formations ranging from soft soil to ultra-hard rock.
Key Specifications & Applications
BQ Core Bits:
Bit diameter: 43.0mm | Compatible core barrel: BQ | Optimal drilling depth: ≤200 meters
