With a weight of 172 Kg (379 Ib), it offers exceptional structural ruggedness and operational stability. Its drill diameter ranges from 65-165 mm, covering the most demanding large-scale blasting hole needs. Notably, its 48 kW high-output hydraulic power delivers unmatched impact force. It excels in deep underground tunnels and high-volume open-pit mines, tackling extreme heavy-duty tasks with ease.
This Hydraulic Drifter undergoes rigorous factory quality inspections. It ensures 100% compatibility with Atlas Copco/Epiroc jumbo drill rigs. Moreover, it eliminates critical flaws of non-original parts: insufficient power, structural fragility, and frequent breakdowns. Even in harsh extreme conditions (high pressure, continuous vibration, heavy dust), it maintains consistent peak performance.
Its precision-machined structure uses aerospace-grade high-strength alloy components. This design ensures fast, accurate drilling with minimal wear. In addition, the advanced triple-sealed system provides superior corrosion resistance. It effectively repels moisture, hydraulic oil erosion, and abrasive particles, extending service life by 30% compared to standard models.
As a dedicated Hydraulic Rock Drill for heavy-duty rigs, it features intelligent power distribution. It maximizes drilling productivity while reducing fuel consumption by 15%. Furthermore, it lowers long-term operational and maintenance costs for mining companies. This makes it ideal for long-duration, high-intensity drilling projects.
Short delivery time ensures timely equipment replacement or fleet expansion. Competitive pricing provides cost-effective solutions for heavy-duty equipment needs. Importantly, original factory quality assurance guarantees long-term performance stability. It minimizes downtime and project delays, keeping critical operations on schedule.
Whether for deep underground tunnel excavation (up to 1000m depth) or coal mine drilling, it delivers reliable results. For high-volume open-pit quarry blasting, it maintains efficiency in extreme weather (high temperature, heavy rain). Specifically, it adapts to poor ventilation in deep tunnels and drastic temperature fluctuations in open pits.
Non-original drifters often fail under extreme heavy loads or long-duration use. They lead to costly repairs, prolonged downtime, and significant productivity losses. In contrast, the COP 1238 Drifter retains structural integrity and performance consistency. It empowers your jumbo rigs to operate at peak efficiency, driving productivity, safety, and profitability in extreme drilling environments.
