YT28 air leg rock drill is a new and efficient rock drilling machine. It is suitable for drilling horizontal, tilting and vertical blast holes in medium-hard rock (f=8~18) with the general diameter of 34~42mm and its effective economic drilling depth can reach 5m. It can be both used together with our FT160 air leg and installed on a drilling rig or rack.
The rock drill is equipped with FY200A lubricator to guarantee good lubrication.
