A integral drill rod is a rock drilling tool where the shank, rod, and bit (or conical head) are machined into a single, non-removable structure. It features a one-piece design with no threaded connections or splicing parts. Due to its monolithic structure, it requires no connections and allows for quick assembly and disassembly, making it particularly suitable for handheld or pneumatic-legged lightweight rock drilling equipment. It plays an irreplaceable role in small to medium-sized projects and localized auxiliary construction.
In mining operations, including underground operations in metal mines, non-metal mines, and coal mines, integral drill rods are commonly used for shallow hole excavation, stope drilling, and roadway preparation. They are suitable for medium-hard and hard rock conditions with hole depths typically ranging from 0.5 to 6 meters, aiming for efficient, flexible, and low-cost operations.
In quarrying and stone processing, integral drill rods are one of the drilling consumables. Quarries have extremely high demands for flexible drilling, localized finishing, and block segmentation, making the rods the most economical and efficient choice. They can be used for down-the-hole drilling of granite, limestone, marble, and other stones; secondary crushing and decomposition of large rocks; and handling of dangerous rocks.
In urban construction, a large number of small, localized, and rapid rock drilling tasks utilize integral drill rods as well. They are used for pre-splitting holes before the demolition of concrete pavements and old buildings, rock breaking of foundations, localized treatment of foundation pits, rock excavation for pipeline and cable trenches, landscape stones, and small-scale projects.
In transportation infrastructure, integral drills are commonly used for small-scale drilling, reinforcement, and emergency repairs. Due to their high mobility and fast construction speed, they are suitable for mobile field operations, such as slope reinforcement, anchor hole and grouting hole construction, roadbed rock breaking, road cut excavation, dangerous rock clearing, early drilling for landslide control, and local rock drilling for bridge and culvert foundations.
In tunnels and underground engineering, it is particularly suitable for areas with limited space where drilling equipment cannot be deployed. The footprints of the integral drill can be seen in shallow hole excavation of small tunnels, water diversion tunnels, and culverts, as well as in tunnel outline trimming, local fracturing, advanced support, anchor bolt holes, and drainage hole drilling.
The integral drill rods are mainly hexagonal shank (Hex 19×108mm, 22×108mm, 25×108mm/159mm), compatible with handheld/pneumatic rock drills, small hydraulic rock drills, and light-duty top hammer drills. The rods provided by Guizhou Gold Drills Equipment Co., Ltd are compatible with Chinese and international rock drills, such as Epiroc (COP 1038, COP 1132, COP 1238, COP 1440, YT28/YT2, COP RR11/RR14, COP MD20 series), Sandvik (TAMROCK HL series, Ranger small handheld drills), Ingersoll Rand (7655, YT28, Y24 series), Furukawa, Montabert, etc. It can also be used with conventional rock drills in China, such as YT23, YT24, YT27, YT28, YT29A, 7655, Y19, Y20, and Y24.
With extensive experience in the drilling industry, Gdrills, as a professional integral drill rods supplier China, can provide integral drill rods compatible with multiple rock drill models and application scenarios such as mining, quarrying, tunneling, highway construction, slope protection, municipal engineering, water conservancy construction and etc.
