This NQ series bit features multiple cutting edges, making drilling progress smoother and reducing the risk of jamming even in complex formations.
During the manufacturing process, the diamonds are fully utilized without erosion, maximizing their cutting potential and extending the bit’s service life. The NQ bit is available in various configurations, including multiple crown profiles ("W", "Flat", "Semi-round", "Cross", "Gear") and matrix heights (6mm-8mm for cost-effectiveness, 8mm-10mm for long service life, 12mm-16mm for super service life), allowing rational selection according to the hardness and abrasiveness of the formation to be drilled.
Standard specifications for the NQ series include NQ, NQ-3.032, NQ2, NQ2-RSG, NQ3/NQTT, NQ3-RSG, NQ3-3.032, NMLC, NWG(NX), NWM, NWT, TNW, with an outer diameter of 75.19-75.44mm and inner diameter of 47.5-47.75mm.
It supports various waterway designs for better flushing in different ground conditions and drilling systems, and is compatible with standard Q threads as well as custom thread types required by clients. Whether for general mineral exploration or complex geological surveys, the NQ Impregnated Diamond Core Drill Bit delivers reliable performance and easy operation, providing a solid foundation for your drilling needs.
