    1.Introduction of YT29A air leg rock drill

    YT29A air leg rock drill is a heavy-duty air rock drill with high efficiency and low consumption. It is especially suitable for construction in railway, highway, hydropower , etc. As a replacement product, it is also a mine roadway for metallurgy, coal and other rock drilling operations.

    YT29A air leg rock drill is suitable for drilling horizontal and inclined holes on medium-hard and hard (f=8~18) rocks. It can also drill the mast hole upwards. The diameter of the blast hole is generally 34-45 mm, which is an economical and economical drill. The hole depth is 5 meters. According to the section size and working conditions of the roadway, it can be equipped with FT160A type air leg, FT160C type long air leg, FT160B type short air leg or FT170 type air leg. It can also be used for dry and wet rock drilling with drill carriage or drilling frame.
