YT27 air leg rock drill is a new type of high-efficiency rock drilling equipment. It is mainly used for rock drilling operations in mine roadway excavation, and is also widely applied as a rock drilling tool in the fields of railway, water conservancy and national defense rock-soil engineering.
 
The YT27 air leg rock drill must be matched with FY250 oil injector and FT160A (or FT160B) air leg. It can carry out wet rock drilling operations in medium-hard and hard rock. The equipment can drill horizontal and inclined blasting holes. After removing the air leg, it can also be installed on a rock drilling jumbo for operation.
