RC Drill Rod Structure
Outer Tube: The outer tube, or barrel, of the drill rod provides the structural integrity and houses the inner tube. It is responsible for transmitting the rotational force and weight to the drill bit, and its threaded ends connect to other rods to form the drill string.
Inner Tube: The inner tube is a sealed conduit that runs through the center of the outer tube. It’s designed to carry the cuttings and rock chips (the “samples”) from the drill bit’s face back up to the surface.
Annular Space: The space between the inner and outer tubes is known as the annular space. This is where compressed air is pumped down the rod string. The air exits through a port at the bit face and forces the cuttings up the inner tube.
Threads: Both the inner and outer tubes have corresponding threaded connections. These threads are precision-machined to ensure a tight, secure seal, which is critical for maintaining the air pressure and preventing sample contamination. The connections are designed for quick make-and-break.
Reverse Circulation Drill Rod Applications
Superior Sample Integrity: The dual-wall design of RC rods ensures that drill cuttings are transported to the surface through the inner tube, completely sealed from the borehole walls. This minimizes contamination from different rock strata, providing a high-quality, representative sample for accurate geological analysis.
Faster Drilling Rates: RC drilling is significantly faster than traditional core drilling methods. The continuous and efficient removal of cuttings via compressed air keeps the drill bit clear of debris, allowing for higher penetration rates and reducing overall project time and costs.
Cost-Effectiveness: The combination of faster penetration rates, reduced rig time, and high sample quality makes RC drilling a highly cost-effective method. It reduces the need for expensive core handling and processing, and the durable rods require less maintenance, further lowering operational expenses.
Environmental Advantages: RC drilling is a more environmentally friendly option compared to other methods that use large amounts of water or drilling mud. It produces less waste and has a smaller footprint, making it ideal for remote or environmentally sensitive areas where water conservation is a priority.
Various RC Drill Rods
RC drilling rods with metzke thread
We offer a premium range of RC drill rods with Metzke thread, a leading connection system known for its exceptional strength and reliability. The Metzke thread design ensures superior torque transmission and resistance to wear, enabling faster and more efficient drilling. Our rods are manufactured from high-grade materials and are engineered for seamless compatibility and long-lasting performance in the most demanding drilling environments.
Remet Thread RC Drill Rods
We supply RC drill rods with Remet thread, another popular and reliable thread type in the industry. The Remet thread is known for its excellent durability and resistance to wear, ensuring a secure and long-lasting connection between rods in challenging drilling environments.
Matrix Thread RC Drill Rods
We provide RC drill rods with Matrix thread, which is designed for robust performance in tough conditions. This thread system offers strong, stable connections, and its specific design helps prevent thread seizing and galling, which can be a common problem with other thread types.
Dual-Tube RC Drill Rods
We offer high-performance dual-tube RC drill rods, the core of reverse circulation technology. This structure features an inner and outer pipe, enabling the simultaneous delivery of compressed air and the return of cuttings, ensuring a clean and uncontaminated sample every time.
RC Drill Rods with Saver Sub
We supply RC drill rods with an integrated saver sub, a crucial component for protecting the main rods. The saver sub absorbs the majority of wear and tear, extending the lifespan of the more expensive rods and allowing for a more cost-effective maintenance and replacement strategy.
RC Drill Rods with API Threads
We supply RC drill rods with API (American Petroleum Institute) threads. While more common in oil and gas drilling, API threads provide a robust, standardized connection for deep drilling. This makes them a reliable choice for RC projects that require a strong, secure, and widely compatible thread system.

Threading
We focus on precision threading for our RC drill rods, a critical aspect for a secure and long-lasting connection. Our threads are machined to tight tolerances to ensure easy make-and-break connections, minimize wear and tear, and maximize the transfer of torque and force, enhancing drilling efficiency.
Material
We select only high-grade materials for our RC drill rods, typically premium alloy steels. This ensures exceptional strength and durability, enabling our rods to withstand the high stress and abrasive conditions of reverse circulation drilling, thereby extending their service life and reliability.
Heat Treatment
We employ a meticulous heat treatment process on our RC drill rods to optimize their mechanical properties. This process increases hardness and toughness, improving resistance to wear, abrasion, and fatigue. The result is a robust rod that maintains its integrity and performance in tough environments.
Dual Wall Structure
We engineer our RC drill rods with a seamless dual wall structure, the core of reverse circulation technology. The concentric inner and outer tubes are designed to prevent contamination by ensuring cuttings travel up the inner tube, allowing for accurate sample recovery with every run.
