YN27C Internal-Combustion Rock Drill

YN27C Internal-Combustion Rock Drill
Self-Powered Portable Gasoline Rock Drill For Remote Working Environments

The YN27C Internal-Combustion Rock Drill is a professional portable rock drilling machine developed for projects where electricity and compressed air are unavailable. Unlike conventional pneumatic rock drills, the YN27C integrates a gasoline engine, air compressor, percussion mechanism, and rotary drilling system into a single compact machine, allowing operators to drill efficiently without external equipment.

Its lightweight construction and self-powered design make it especially suitable for mountain projects, remote mining sites, road maintenance, railway construction, hydropower engineering, geological exploration, and emergency rescue operations.

Besides drilling, the YN27C can also be used for breaking, splitting, tamping, and chipping by changing its operating mode, making it one of the most versatile portable drilling machines available.

Advanced Self-Powered Drilling Technology

Unlike pneumatic rock drills, the YN27C generates compressed air internally using its built-in gasoline engine.

Working Principle

The drilling process includes:

Start the integrated gasoline engine.
The built-in compressor generates compressed air.
The percussion piston delivers high-impact energy.
The drill rod rotates continuously.
The drill bit penetrates the rock.
Internal air flushing removes drilling debris.

This integrated design provides:

Completely self-powered operation
No external air compressor required
No electrical power required
High drilling efficiency
Easy transportation
Excellent field mobility
