Your Trusted Drill Rod Manufacturer from China

nq drill rods

Sinodrills is your trusted drill rod manufacturer from China, specializing in high-quality drilling tools. We use advanced manufacturing techniques and premium materials to produce a wide range of drill rods, including NQ and W1. Our commitment to durability and precision ensures that our rods provide reliable performance and excellent service life for all your drilling needs.

NQ drill rods feature specific thread specifications designed for fast and reliable connections in wireline core drilling. These threads are critical for transmitting rotational torque and pulling forces while allowing the inner tube to be retrieved without pulling the entire drill string.

  • Tapered, Coarse Threads: NQ rods are characterized by a tapered, coarse thread profile with a pitch of three threads per inch. This design allows for quick “make-and-break” connections, saving time during the drilling process.

  • Thread Pitch and Pin Length: The standard thread pitch is typically 3 threads per inch (TPI). The pin length on the threaded end is generally around 44.45 mm (1.75 inches). These dimensions ensure a secure and stable joint between individual rods.

  • Heat Treatment: To enhance durability, the threads on NQ drill rods often undergo a specific heat treatment process. This increases their hardness and wear resistance, preventing galling and seizing, which can be a common issue with threads of equal hardness.

  • Load Efficiency: The thread design provides a specific load efficiency (typically around 30%), which is the ratio of the joint’s load-carrying capacity to the strength of the rod’s main body. This ensures sufficient strength for most drilling conditions.

Q Series Drill Rods

Q-series drill rods are a specific type of wireline drill rod designed for core drilling. They are known for their proprietary tapered, coarse threads that facilitate easy and quick make-and-break connections. The “Q” designation, originally a proprietary product by a major manufacturer, has become a widely recognized standard in the industry for various sizes of wireline rods.

AQ Drill Rods

AQ drill rods are the smallest size in the Q-series. They are used for drilling shallow holes and obtaining core samples in applications where a smaller diameter is sufficient, such as in geotechnical or environmental investigations.

BQ Drill Rods

BQ drill rods are slightly larger than AQ rods and are a popular choice for many standard-depth wireline drilling projects. They offer a balance of strength and maneuverability, making them suitable for a wide range of geological formations and conditions.

NQ Drill Rods

NQ drill rods are a widely used size in mineral exploration and geotechnical drilling. They provide a larger core sample than BQ rods, allowing for better geological analysis, and their robust design can handle deeper and more demanding drilling operations.

HQ Drill Rods

As a larger-diameter option, HQ drill rods are employed for drilling in soft or fractured ground, or when a larger core sample is required for detailed analysis. They are designed for greater strength to handle the increased loads of deeper and more challenging drilling.

PQ Drill Rods

PQ drill rods are the largest size in the standard Q-series. They are primarily used for drilling in very soft formations or when a high-quality, large-diameter core sample is essential. Their size and strength allow for deeper drilling in less consolidated ground.

Drill Rod Applications​

Drill rods are a fundamental component in a wide array of drilling applications, serving as the crucial link between the drill rig and the cutting tool. Their design and material are tailored to meet the specific demands of each industry, ensuring efficient and effective drilling in diverse geological and environmental conditions.

Mineral Exploration

Drill rods are vital for core drilling to extract rock samples from deep underground. This allows geologists to analyze mineral content, rock formations, and geological structures. The rods must be strong enough to withstand high torque and stress while maintaining precision for accurate core retrieval.

Geotechnical Investigation

In construction and civil engineering, drill rods are used for geotechnical sampling to assess soil and rock properties. This data is critical for designing foundations, tunnels, and other infrastructure. The rods must be robust enough to penetrate various strata while preserving the integrity of the collected samples.

Quarrying and Mining

Drill rods are a key part of the blast hole drilling process in quarrying and open-pit mining. They transmit the percussive and rotational force to create holes for explosive charges. The rods must be highly durable and resistant to fatigue to endure the continuous impact and abrasion.

Environmental Drilling

In environmental projects, drill rods are used for collecting soil and groundwater samples to monitor contamination and pollution. The drill rods often have to be made from specialized materials like stainless steel to prevent cross-contamination and ensure the integrity of the environmental samples.
