Description
Integral drill rod is a one-piece drilling component made of high-strength alloy steel, designed for efficient rock and soil drilling. It integrates rod body and drill bit connection, avoiding assembly gaps, and ensures stable force transmission during operation, suitable for medium to heavy-duty drilling tasks.

Product Advantages
Structural Strength
Utilizing an integral molding process, the entire drill rod is free of any weld joints. This design fundamentally eliminates the inherent risk of fracture at connection points; under actual operating conditions, the rod breakage rate is reduced by over 60% compared to standard segmented rods.
Drilling Precision
Straightness deviation is strictly controlled (≤ 0.5 mm/m), keeping borehole deviation within 1%. The resulting boreholes are positioned with extreme precision, effectively resolving the common construction challenge of drill bit jamming.
Durability
Manufactured from high-grade 95CrMo alloy steel, the entire rod body undergoes a comprehensive hardening treatment. Its average total drilling footage exceeds that of segmented rods by over 30%, significantly extending the replacement cycle.
Construction Efficiency
The Integral Drill Rod is ready for immediate use on-site, requiring no assembly of drill bits; the replacement process saves over 50% of the time typically required by traditional methods. Furthermore, its optimized weight makes handling and loading/unloading less physically demanding for workers.
Main Applications
- Mining: Used for ore and coal seam drilling with integral drill rod, adapting to underground harsh environments.
- Construction: Applied in foundation pile drilling and wall hole-making for buildings.
- Road & Bridge: Used for subgrade exploration drilling to test soil bearing capacity.
- Water Conservancy Projects：In reservoir and dam construction/maintenance, integral drill rods drill for foundation exploration, drainage, and grouting to ensure stability, anti - seepage, and drainage.
- Geothermal Development：For geothermal energy extraction, integral drill rods, with high strength and stability, drill deep wells under high - temp/high - pressure conditions.
- Municipal Engineering：In urban projects like pipeline laying and underground parking lot building, integral drill rods drill holes for pipeline and support structure installation.
Factory Profile
Leveraging the comprehensive industrial supply chain advantages of the Beijing-Tianjin-Hebei region, we specialize in the manufacture of integral drill rods and drilling tool accessories. Our facility is equipped with multiple CNC machining centers and a dedicated heat treatment line; every product batch undergoes rigorous sampling inspections for hardness, straightness, and impact resistance. We offer customization services for non-standard lengths and diameters based on client drawings or samples, with standard orders typically shipping within 5–7 days. Our products currently serve numerous domestic mines and drilling rig manufacturers, and are also exported to markets across Southeast Asia, Africa, and other regions.
FAQ
Q: What are the export protection standards for your products?
A: We employ a "triple-protection" standard: independent packaging (rust-inhibiting oil + protective sleeve) combined with structural reinforcement (wooden crates or steel frames). This ensures that our products remain free from rust and structural damage, even within the harsh environment of maritime transport.
Q: What is the maximum drilling depth capability of your Integral Drill Rods? Are they capable of handling hard rock?
A: The standard length range covers 0.4m to 6m, with a customization limit extending up to 10m. Under typical medium-hard rock conditions (f=8–12), the 6m-specification integral drill rod is capable of completing a full hole in a single pass, thereby significantly reducing downtime associated with rod changes.
Q: Are there any specific requirements regarding the rock drill models used with your products?
A: Our products offer broad compatibility. They are compatible with mainstream air-leg drills (such as the YT28/29A), handheld drills, and small-scale hydraulic drilling rigs. We offer a variety of standard shank sizes-including B19, B22, and B25-and provide tailored matching services to ensure perfect compatibility with our customers' specific equipment models.
