Applications of Internal Combustion Rock Drill
Quarrying
Used for blasthole drilling, secondary breaking, and slope trimming in quarries.
Road Construction
Ideal for slope anchoring, grouting, drainage holes, and road foundation breaking.
Rescue
Reliable for obstacle removal, concrete breaking, and emergency disaster relief work.
Exploration
Suitable for geological survey, prospecting holes, and field sampling drilling.
Municipal Work
Applied in pavement demolition, trench excavation, and urban construction projects.
Competitive Advantage
Self-Contained Power
The YN27C has a built-in gasoline engine, eliminating the need for compressors, generators, or air hoses. It is ideal for remote, off-grid, and fast-moving job sites.
2-in-1 Functionality
By changing accessories, the YN27C can handle both drilling and breaking work, helping reduce equipment investment and improve jobsite flexibility.
Portable & Field-Ready
Its compact 27 kg design makes it easy to carry and operate in mountains, slopes, narrow spaces, and other hard-to-reach outdoor environments.
Durable Core Components
Key parts use high-strength alloy steel with advanced heat treatment for longer service life, reliable performance, and lower downtime during continuous operation.
Fuel-Efficient & Safer to Use
The optimized engine lowers fuel consumption and operating cost, while the muffler and spark arrester improve safety and reduce noise in outdoor working conditions.
