YT27 Portable Air Leg Rock Drill Rock Drilling Machine For Quarry And Construction
Product Description
The YT27 air leg drill is a highly efficient and lightweight machine, ideal for wet drilling down and tilting holes in medium hard to hard rocks (F=8-18). It features a drilling hole diameter of 34-45 mm and an effective drilling depth of up to 5 m. With superior blowing-cleaning hole function and high torque, it outperforms similar products in its class.
The YT27 air-leg rock drill combines the advantages of the YT23 drilling rig with advanced features like a flange control valve for gas production. It is perfect for large-scale mining and tunnel drilling operations, as well as applications in railway, water conservancy, and national defense stone engineering. It can be paired with the FY250 type oil injector and FT160A/B type air leg for wet rock drilling of medium and hard rocks, drilling horizontal and inclined gun holes, and can also be mounted on a platform car when the air leg is uninstalled.
Key Features
- Easily-accessible throttle position
- Integral muffler for reduced noise
- Reliable structure for easy and stable operation
- Compatible with both hand-held and air-leg rock drilling
- Optimal combination of performance and economy—smart and durable
