1. The YT27 air-legged rock drill is suitable for wet drilling horizontal and inclined shell holes in medium to hard rock, with an effective economic drilling depth of up to 5 m. It can be used with the FT140B air-leg depending on the size of the roadway section, and can also be installed on a dolly or drilling frame.
2. The YT27 air-legged rock drill is a new type of high-efficiency rock drilling machine, which is mainly used for rock drilling in mine roadway excavation, and is also a widely used rock drilling tool in railway, water conservancy and national defence projects, and can be used with the FY250 oiler and FT160A (or FT160B) air-leg to drill horizontal and inclined holes in medium and hard rock, and can also be installed on a dolly with the air-leg removed.
