•The rock drill is a kind of high efficiency air leg rock drill machinery. It is mainly used

for diging into mine laneway and blasting holes in all drilling works. It is indispensably

importance machine tool in metallurgy, coal, railway, traffic, water conservancy construction

and national defence stone project.
•It is suitable for drilling and blasting under various of rocks at any direction angles. Blast

hole dia is 34-42mm,drill hole depth is 5 m This machine may match with Model FT160BD short air

leg or Model FT160BC long air leg.
•This machine has transparent surface of FY200B oil reservoir, easy to observe the oil lever,

adjust oil quantity, ensure the well lubricated.
