YO-18 portable dual-purpose air leg rock drill is a light rock drilling machine. It can be used for downward dry drilling in secondary blasting and stonework of mines and quarries. After being equipped with FT100 air leg, it can be used as an air leg rock drill for wet drilling of horizontal and inclined blast holes in small cavities. As the machine has the advantages of small air consumption, light weight, large torque and simple structure, it can be used together with small air compressor. It is easy to operate and repair, therefore, it is an ideal light rock drilling tool.
