KATDRILLS YN27J Rock drill
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.
YN27J 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.

Application
Ideal for mining, quarrying, road construction, tunneling, municipal works, and emergency rescue. Perfect for small-scale rock drilling, blasting preparation, slope stabilization, foundation work, and rock breaking in areas without power access.
Advantages
Superior Power & Fuel Efficiency
Optimized engine components deliver stronger, more stable power output and significantly improved cold-start performance, ensuring easy startup even in low-temperature or harsh environments.
Enhanced fuel combustion efficiency cuts fuel consumption and extends operating range, reducing frequent refueling and lowering operational costs.
Lightweight & Ergonomic Design
Lighter overall weight than YN27C for easier single-person handling and handheld operation.
Redesigned handles and body layout minimize vibration and noise, offering better ergonomics and reducing operator fatigue during long working hours.
Upgraded Heat Dissipation for Extended Continuous Operation
Improved cooling system (optimized air ducts, enhanced heat sinks) prevents overheating shutdowns, extending continuous working time by over 30% compared to YN27C-ideal for high-intensity, long-duration rock drilling.
Enhanced Durability & Easier Maintenance
Key components (cylinder, piston, gears) use high-strength wear-resistant materials, with upgraded sealing for better dustproof, waterproof and impact resistance, prolonging service life.
Simplified replacement of wearing parts (spark plug, filter) and extended maintenance intervals reduce later maintenance costs and downtime.
Higher Drilling Efficiency & Flexible Function Switching
Tuned impact frequency and torque enable faster drilling speed, suitable for harder rock formations (granite, basalt).
Effortless switching between drilling, breaking, tamping and other functions without complex adjustments, boosting multi-purpose efficiency.
Upgraded Safety Features
Added overheat protection and anti-misoperation devices prevent engine damage from overheating and safety risks from incorrect operation, ensuring safer construction.
