With its reinforced extreme-resistant + high-frequency integrated structural design, it balances powerful performance, operational flexibility, and precision drilling—ideal for underground deep tunnels (high pressure/extreme vibration) and open-pit extreme sites (low temperature/high corrosion). Its hole range of 51-89 mm perfectly covers medium to large-diameter precision blasting hole requirements, while the 16 kW impact power delivers consistent, energy-saving drilling force. Notably, the 73 Hz impact frequency (4380 bpm) ensures ultra-fast drilling efficiency, and the specialized extreme-resistant coating enhances durability in harsh environments—making it a top choice for mid-large projects in extreme working conditions.

This Hydraulic Rock Drill undergoes strict factory quality control and extreme-resistant high-frequency heavy-duty precision testing. It ensures 100% compatibility with standard and mid-large capacity jumbo rigs, eliminating critical flaws of non-original parts: unstable load-bearing, imprecise drilling, poor extreme-environment adaptability, and frequent malfunctions. Even in harsh conditions (extreme pressure, extreme vibration, heavy dust, wetness, high corrosion, -35℃ to 65℃ temperature range), it maintains consistent peak performance—backed by original factory manufacturing standards.

Its precision-machined structure uses high-strength corrosion-resistant alloy + premium wear-resistant/shock-absorbing composite materials. The integrated extreme-resistant and high-frequency design enhances drilling stability, efficiency, and environmental resilience while preserving accuracy—core advantages of the “COP 1640EX+” series. In addition, the multi-layer sealed system + anti-abrasive/anti-corrosion/anti-temperature-shock coating provides all-around protection against moisture, dust, corrosion, and extreme temperature fluctuations. It extends service life by 52% compared to ordinary mid-large hydraulic drifters.

As a mid-large extreme-resistant high-frequency Hydraulic drifter, it features practical adaptive control technology. It automatically adjusts drilling parameters based on real-time rock hardness and environmental data—complementing its 200 bar hydraulic pressure to ensure smooth, high-speed operation even in extreme conditions. This maximizes drilling productivity (38% faster than conventional heavy-duty models) while reducing fuel consumption by 29%. Furthermore, its compatibility with multiple enhanced shank adapters (R32E/TC35E/T38E/T45E/T51E) enhances universal adaptation, supporting seamless integration with diverse jumbo rig configurations.

Short delivery time ensures timely equipment replacement or project startup—critical for mid-large mining and construction companies operating in extreme areas. Competitive pricing offers high-cost-performance solutions, especially for enterprises needing extreme-condition high-frequency drilling reliability. Importantly, original factory quality assurance guarantees long-term operational stability, reinforced extreme resistance, and low maintenance costs. It minimizes downtime (less than 0.6% annual failure rate) and project delays, supporting continuous production in extreme mining environments.

Whether for mid-large underground mine drilling (high temperature/high corrosion), deep tunnel excavation (high pressure/extreme vibration), open-pit large-scale blasting (low temperature/heavy dust), or high-frequency heavy-duty precision drilling tasks, it delivers reliable, high-precision results. For underground operations, its rugged design withstands extreme pressure and vibration; for open-pit projects, it resists low temperature and high corrosion while handling medium to large-diameter blasting holes with ultra-fast efficiency. Specifically, it adapts to hard rock mines, medium-hard rock tunnels, high-pressure underground sites, dusty/wet/open-pit quarries, and high-corrosion mining areas—meeting diverse mid-large extreme high-frequency heavy-duty precision drilling needs.

Non-original hydraulic drifters often lack extreme-environment resistance, high-frequency efficiency, or durable structures. They lead to extra maintenance costs (3x higher than original parts), low productivity, and significant financial losses for mid-large enterprises. In contrast, the COP 1640EX+ Hydraulic drifter retains structural integrity, extreme-resistant high-frequency precision, and reliable efficiency at a competitive price. Its advantages (extreme-environment adaptation, high-frequency drilling, wide hole range, multi-enhanced adapter compatibility, cost-effectiveness) empower your jumbo rigs to operate at peak efficiency, driving profitability in mid-large scale extreme mining projects.
