Product Description

   Montabert  brand rock drills are currently the leading brand of rock drills, with mature technology, leading technology, and excellent quality. They are widely used in various fields such as mining, tunnel excavation, water conservancy engineering, and road construction. They have the characteristics of high efficiency and high return rate, and can effectively reduce engineering risks and labor intensity.                        HC95 LM Hydraulierc Rock Drill
1. High input/output efficiency ratio, for reduced and optimized energy consumption
2. Latest generation of patented proactive hydraulic dampener, improving shanks and bits life span
3. Standard configuration with stainless steel front end
4. High-capacity HP nitrogen accumulator granting high and constant impact energy
5. Energy recovery system boosting impact rate for better penetration results
6. Strong and economical rotation system allowing large reaming holes
7. Standard configuration with hydraulic reverse percussion, allowing long hole drilling applications
8. The shortest drifter in its category; longer holes for the same feed size
9. No tie rods; single body drifter prevents seizing and breakage issues
10. No need to re-inflate accumulators between overhauls
11. New patented anti-cavitation sealing system, increasing intervals between overhauls
12. New drifter concept with less parts for handy maintenance
