The Internal Combustion Rock Drill Type YN27J is a very efficient machine with the characters of the structure is very compact, less of the- easy-to-damage-parts, and very easy to control. It can adapt to these outside situations there is no water and electronic power.

It is a kind hand held drill built up with gasoline engine, air pump, rock drill and the rotation plumbum equipment for running or stop. It can be used as a tool for breaking, percussive drilling, tamping besides rock drilling.

Five Core Advantages of the YN27J Gasoline Rock Drill

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℃ high heat to -40℃ severe cold.
• Particularly suitable for engineering projects in areas lacking infrastructure such as high mountains, plains, and remote mountainous regions.

2. Easy Operation & High Efficiency with Less Effort

• Simple start-up with just a handle rotation, no professional training required.
• Drilling speed of ≥250mm/min, several times higher than traditional manual rock drilling.
• Automatic slag blowing function: compressed air generated during operation clears rock dust automatically to keep the drill hole unobstructed.
• Operable by one person alone, significantly reducing labor intensity.

3. Compact Structure, Lightweight & Durable

• Total weight of only 27kg and small size (746×315×229mm), facilitating easy carrying and transportation.
• Manufactured with high-strength materials, featuring a stable structure and excellent impact resistance.
• Few wearing parts, simple maintenance, and long service life.
• Parts are fully interchangeable with international similar products, ensuring convenient maintenance.

4. Fuel-Efficient & Long Endurance

• Low fuel consumption design: ≤0.12L/m (fuel consumption per meter of drilling).
• Large-capacity fuel tank (≥1.5L), supporting continuous operation for several hours on a full tank.
• Special carburetor design maintains stable combustion efficiency even in high-altitude areas.

5. Multifunctional Application for Various Working Conditions

• Capable of vertical downward drilling (maximum depth of 6 meters) and upward drilling at <45°.
• Suitable for multiple scenarios including mining, road construction, bridge construction, and geological exploration.
• Can be quickly converted into a crusher or rammer, achieving multiple uses in one machine with high cost-effectiveness.
