The YT29A Air-Leg Rock Drill is a new generation of high-efficiency pneumatic machinery designed for the most demanding drilling operations. It is the premier choice for roadway excavation and various rock drilling tasks in mines, railways, and highways. Engineered for power and reliability, the YT29A excels in drilling horizontal and inclined blastholes, particularly when paired with our FT160 or FT170 series air-legs.
● Superior Power & High Torque: With impact energy reaching up to 78J, the YT29A is engineered for high-performance drilling in hard and super-hard rock formations.
● Optimized for Tunneling & Drifting: The grouped control valve mechanism provides fast start-up and easy, responsive handling, making it the ultimate tool for roadway excavation.
● High-Efficiency Performance: A high drilling shock frequency and torque ensures rapid penetration, saving time and reducing operational costs on large-scale projects.
● Robust and Long-Lasting: Built for durability, the YT29A guarantees a long service life and reliable performance in the most challenging mining and construction environments.
