When YS STEEL's factory was manufacturing this Mining rock drill rod, they selected high-toughness alloy steel specifically for mining, taking into account both impact resistance and bending fatigue resistance. The threads are not prone to breakage, and the rod body is wear-resistant and corrosion-resistant.
It covers mainstream thread specifications such as R32, R38, T38, T45, and T51, and the length can be adjusted as needed, compatible with most imported and domestic hydraulic top-hammer rock drilling machines on the market.

Mining-specific alloy steel forging, balanced strength and toughness, effectively preventing the drill rod from breaking during hard rock drilling, suitable for complex geology.
Both ends of the threads are precision-turned and finely processed and locally strengthened, anti-impact, anti-tearing teeth, anti-slip grooves, more stable force transmission, longer service life.
Magnetic particle full inspection to check for internal cracks and layers, eliminating hidden problems at the source, ensuring the safety of mining construction.
Optimize the forging texture to enhance bending and fatigue resistance, shock resistance, anti-breakage, suitable for skewed holes, high-frequency vibration conditions.
Can be upgraded with surface anti-corrosion and wear resistance as needed, supports non-standard lengths, special thread customization, suitable for various mining environments.
A1: It is mostly due to thread breakage and slipping, rod body fracture, excessive wear of the rod body, and is often related to air drilling, insufficient lubrication, deviation of the drilling hole, and frequent impact from hard rocks. If there are deformation cracks, the drill should be immediately stopped.
A2: Yes, old parts can be sent back for measurement. Non-standard lengths, special threads, and reinforced surfaces can all be customized.
A3: We have a complete production and testing line of our own. We are integrated in trade and manufacturing and support online video factory inspection.
A4: Regular standard specifications for spot goods take 3-7 days to be delivered; the delivery time for non-standard products is based on the complexity of the process.
A5: No, the threads must match the drilling machine and drill bit specifications. Mixing them can easily lead to breakage accidents.
A6: It only covers raw materials and manufacturing defects. Geological wear, overload impact, and improper operation are considered normal wear and do not fall within the warranty scope.
A7: Supported. It can be combined with third parties to complete measurements, mechanics, non-destructive testing, and issue corresponding documents.
