1.Description
Our customizable diamond core drill bits, available in BQ, NQ, HQ, and PQ sizes, are engineered to seamlessly integrate with wireline coring systems, offering tailored solutions for diverse drilling challenges. Whether you’re working in soft soil, abrasive sandstone, hard granite, or fractured rock formations, these bits can be customized to match your specific project needs—from matrix hardness and diamond concentration to water hole design—ensuring optimal performance and core recovery.
Key Sizes & Compatibility
Designed to align with global wireline coring standards, each size pairs perfectly with corresponding core barrels, making them compatible with most industry-leading rigs
BQ (43.0mm): Ideal for shallow to medium-depth drilling (≤200m), suited for geological surveys, environmental sampling, and small-scale foundation testing.
NQ (75.7mm): A versatile mid-range option for 200–500m depths, widely used in mineral prospecting, groundwater exploration, and civil engineering.
HQ (96.0mm): Built for 300–800m deep drilling in hard rock, perfect for mining exploration, tunnel construction, and deep borehole logging.
PQ (122.6mm): Engineered for ultra-deep projects (≥500m) in ultra-hard formations, critical for geothermal development and deep mineral exploration.
Customization Options to Meet Your Needs
Matrix Hardness: Adjust from HRC 35 (for soft formations) to HRC 45 (for abrasive/hard rock) to balance wear resistance and drilling speed.
Diamond Concentration: Choose high-concentration (for hard, intact rock) or medium-concentration (for fractured formations) to optimize cost and efficiency.
Water Hole Design: Customize hole size and layout to enhance cooling and debris removal, reducing clogging in high-sediment environments.
Thread Specifications: Match specific core barrel threads (API, metric, or proprietary) for a secure, vibration-free connection.
