Features:
The YT27 rock drill is a new high-efficiency air leg rock drill, primarily used for rock drilling in tunnel excavation in mining operations. It is also widely used as a drilling tool in railway, water conservancy, and national defense stone engineering projects. It is compatible with the FY250 oiler and the FT160A air leg, enabling wet drilling on medium-hard and hard rocks, and drilling horizontal and inclined blast holes. When the air leg is removed, it can also be mounted on a trolley for operation.
1.Powerful Impact Force: The YT27 provides a strong impact energy, making it effective in drilling hard rock formations and increasing efficiency.
2.Sturdy Construction: Designed for heavy-duty use, it is highly durable and performs well in extreme mining conditions.
3.Easy Maintenance: The YT27 is easy to maintain, helping to minimize downtime and ensure consistent productivity.
