The Internal Combustion Rock Drill Type YN27J is a highly efficient machine characterized by a compact structure, fewer easy-to-damage parts, and exceptional control. It is specifically designed to adapt to outdoor environments where water and electronic power are unavailable.
This hand-held drill integrates a gasoline engine, air pump, and rock drill with rotation equipment. Beyond rock drilling, it serves as a versatile tool for breaking, percussive drilling, and tamping.
Five Core Advantages of the YN27J Gasoline Rock Drill
The YN27J is a portable internal combustion gasoline rock drill that combines power and precision in one unit, ideal for field operations.
1 Excellent Environmental Adaptability
- No need for external power or water supply, enabling operation anytime and anywhere.
- Stable performance in extreme temperatures, ranging from 40°C high heat to -40°C severe cold.
- Particularly suitable for high mountains, plains, and remote mountainous regions lacking infrastructure.
2 Easy Operation & High Efficiency
- Simple start-up with just a handle rotation; no professional training required.
- Drilling speed of ≥250mm/min, significantly faster than traditional manual drilling.
- Automatic slag blowing: compressed air clears rock dust automatically to keep holes unobstructed.
- One-person operation reduces labor intensity significantly.
3 Compact Structure & Durability
- Total weight of only 27kg and small size (746×315×229mm) for easy transportation.
- High-strength materials ensure a stable structure and excellent impact resistance.
- Minimal wearing parts ensure simple maintenance and a long service life.
- Parts are fully interchangeable with international similar products.
4 Fuel-Efficient & Long Endurance
- Low fuel consumption: ≤0.12L/m (per meter of drilling).
- Large-capacity fuel tank (≥1.5L) supports continuous operation for several hours.
- Special carburetor design maintains efficiency even in high-altitude areas.
5 Multifunctional Application
- Capable of vertical downward drilling (max depth 6m) and upward drilling at <45°.
- Ideal for mining, road construction, bridge building, and geological exploration.
- Quickly converts into a crusher or rammer for high cost-effectiveness.

Frequently Asked Questions
Q: Does the YN27J rock drill require an external air compressor?
A: No, the YN27J is a self-contained unit that integrates the gasoline engine and air compressor, making it completely independent of external power sources.
Q: What is the maximum drilling depth for this machine?
A: The YN27J can reach a maximum vertical drilling depth of up to 6 meters.
Q: Can it operate in extremely cold weather?
A: Yes, the machine is designed to perform reliably in temperatures ranging from -40°C to 40°C.
Q: What kind of fuel does the YN27J use?
A: It uses a mixture of gasoline and lubrication oil at a volume ratio of 12:1.
Q: Is it difficult to transport to remote areas?
A: Not at all. Weighing only 27kg with a compact design, it is easily portable by a single person, even in mountainous terrain.
Q: Can this machine be used for tasks other than drilling?
A: Yes, by changing the internal components, it can be quickly converted into a breaker or a tamping rammer for demolition and construction work.
