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.
