BQ Wireline Drill Rod
Fully Robotic Automation, Robotized & Automated Processing
Accuracy of threads will determine the use effects and life time of drill rod and casings. CNC latches and form cutter are used in thread opening processing to minimize error made by anthropic factors.
Load efficiency of 30% provides sufficient strength for most drilling conditions
SINOCOREDRILL only choose the best steel tubes in the market to manufacture our rods and pipes. Spot check will be conducted after the steel tubes delivered to company. We will make sure the compositions and specifications match the inspection report form the suppliers.
Whole rod Heat treated significantly increases rod life
Rod Pin thread crest is hardened to nominal 50-55 HRC to eliminate damaging ‘adhesion’ wear Eliminates the transfer of wear material back and forth as seen between threads of equal hardness, leading to large scale galling and joint seizing Heat treatment will greatly improve the material strength and increase the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body. After heat treatment, strength, hardness, straightness and concentrically of the treated tubes will be tested in our lab.
| Size | O.D | I.D | Weight (kg/3m) | Remarks |

| AQ | 44.5mm | 34.9mm | 14.0 | Entire length heat treated, case hardened at two ends |
| BQ | 55.6mm | 46.1mm | 18.0 | |
| NQ | 69.9mm | 60.3mm | 23.5 | |
| HQ | 88.9mm | 77.8mm | 34.5 | |
| PQ | 114.3mm | 101.6mm | 52.2 |

Surface of the threads will be cleaned to remove burr adhered after threads are opened.

| Features | Wireline Drill Rod Vs. | Conventional Drill Rod |
|---|---|---|
| Core Retrieval | Through wireline-no need to pull rods | Must extract full drill string |
| Time Efficiency | Very fast, ideal for deep coring | Slow, labor-intensive |
| Cost per Meter | Lower in deep-hole drilling | High due to tripping time |
| Core Quality | Minimal disturbance; higher recovery | More disturbance risk |
| Best Application | Exploration, mining, geothermal | Shallow or rotary projects |
| Safety | Fewest heavy rod-handling cycles | More manual handling required |
Slightly larger than the AQ, the BQ drill rod offers a good balance between maneuverability and increased core size. It is a popular choice for a wide range of exploration and geotechnical projects, providing larger core samples than AQ while still maintaining relatively high drilling speeds.
BQ rods are versatile, suitable for various ground conditions, and are frequently used when a more substantial core is needed for detailed analysis without moving to the heavier NQ system.
