Product Introduction
The YGZ70 Pneumatic Rotary Drifter is a rock drilling tool powered by compressed air. Designed to be integrated with tunneling machines or umbrella-type drill rigs, this tool is primarily utilized in tunnel excavation operations. It is capable of drilling both horizontal holes and down-the-hole (DTH) bores, covering a range of standard drilling diameters with an effective drilling depth reaching up to several meters. Additionally, the tool features a bi-directional rotation function. Furthermore, the YGZ70 Pneumatic Rotary Drifter is well-suited for rock drilling applications in railway, highway, infrastructure, water conservancy, and quarrying projects.

Product Features
High Efficiency and Power
Offers rapid drilling speeds and increased footage per shift, effectively shortening tunneling or mining cycles and accelerating overall project progress.
Compact Design with High Adaptability
Features a compact body with a drill rod center-to-top clearance of just 80 mm, allowing for flexible operation within narrow roadways without the need to enlarge the roadway cross-section-thereby reducing initial investment costs. Simultaneously, it is compatible with a wide variety of drill rigs, making it suitable for a broad range of application scenarios.
Stable and Reliable Performance
Key components are highly durable, resulting in a low failure rate and minimizing schedule delays caused by downtime. The forward and reverse rotation functions effectively address drill rod jamming issues, reduce wear on drilling tools, and ensure worry-free operation over the long term.
Economical, Efficient, and Energy-Saving
Utilizes a valveless air distribution structure that ensures low air consumption and low maintenance costs, resulting in lower overall operating expenses. A single unit can handle multiple drilling tasks, eliminating the need for redundant investments and offering excellent value for money.
