RD18U Drifter is a core New Original Hydraulic Rock Drill designed for jumbo drill rigs, serving as the backbone of large-scale drilling operations in mining and construction. With a weight of 190 kg, a drill diameter range of 45-127 mm, and a rated power of 33 kW, it excels in both underground tunnel/coal mine scenarios and open-pit quarry/metal mine blasting drilling, meeting the rigorous demands of high-intensity work.

This Hydraulic Drifter undergoes strict factory quality inspections to ensure 100% compatibility with Atlas Copco/Epiroc jumbo drill rigs. It eliminates common issues like low drilling efficiency and frequent malfunctions that plague non-original alternatives, especially in harsh underground or open-pit environments.

Its precision-engineered structure delivers powerful impact force and stable drilling performance. The 33 kW rated hydraulic power converts into high-frequency mechanical impact, enabling fast and accurate blasting hole drilling (45-127 mm) — critical for improving project progress in tunnel excavation and open-pit mining. At 190 kg, it balances portability and stability, fitting seamlessly with most standard jumbo rig configurations.

The RD18U Drifter features high-strength alloy components and a sealed design. It resists dust, moisture, and continuous vibration, maintaining reliable operation in extreme conditions such as underground tunnels with poor ventilation and open-pit sites with temperature fluctuations.

As a dedicated Hydraulic Rock Drill for jumbo rigs, it balances power and energy efficiency. It reduces fuel consumption while maximizing drilling output, making it ideal for long-duration mass drilling projects.

Key benefits include short delivery time and competitive pricing. This makes it a cost-effective solution for mining companies and construction teams needing timely equipment replacement or expansion.

Non-original Hydraulic Drifters often fail to withstand heavy loads or adapt to dual-scenario use, leading to costly downtime and project delays. But the RD18U Drifter maintains structural integrity and performance stability long-term, supported by original factory quality assurance.

Whether for underground tunnel excavation, coal mine drilling, or open-pit quarry blasting, this Hydraulic Rock Drill delivers consistent results. It empowers your jumbo drill rigs to operate at peak efficiency, driving productivity in large-scale drilling operations.
