YT29A Air Leg Rock Drill
The most powerful model in the YT Series for extreme rock excavation challenges
Product Overview
The YT29A Air-Leg Rock Drill represents the pinnacle of performance in the acclaimed YT Series, engineered specifically for the most demanding rock excavation applications. As the most powerful model in the lineup, it combines exceptional impact energy with remarkable portability, making it the preferred choice for challenging mining operations, tunnel construction, and infrastructure projects where maximum drilling power is essential. The YT29A delivers superior performance in hard rock formations while maintaining the reliability and ease of use that have made the YT Series a global standard in pneumatic drilling technology.
Key Features & Performance
Unmatched Impact Power
Features the highest impact energy in the series at ≥78 J, achieved through an advanced 82mm cylinder diameter (larger than previous models), delivering superior rock fragmentation in the hardest formations.
Optimized Power-to-Weight Ratio
Despite its increased power, maintains a lightweight design of only 27 kg - matching the portability of smaller models while delivering significantly more drilling force for reduced operator fatigue.
Precision Engineering
Features a refined internal mechanism with ≥37 Hz impact frequency that ensures consistent, high-speed drilling performance even in the most challenging rock conditions (hardness coefficient f=8-18).
Enhanced Air System
Optimized air passage design handles ≤88 L/S air consumption at standard working pressure (0.4-0.63 MPa), maximizing energy transfer efficiency while maintaining compatibility with standard compressor systems.
Universal Application
Drills precise blast holes of 34-42 mm diameter to a depth of 5 meters at any angle, making it ideal for complex tunneling projects and confined space operations.
Premium Construction
Features hardened alloy components and reinforced stress points throughout the drill body, providing exceptional durability and extended service life in continuous operation environments.
