XY-4 Core Drill is a new type high speed diamond core drill, designed according to the development of geological work in China and developed to meet the requirements of clients.
XY-4 Core Drill has been identified in 1976, and rewarded with the Chinese National Silver Medal in 1988. The XY-4 model has been sold all over the country.
XY-4 Core Drill can be driven by Deutz F4L 912 diesel engine or 30KW electric motor. The drill has 8 rotary speed stage, the Max, speed 1588 rpm, the min speed 101 rpm, so it is suitable for various drilling for solid mineral deposits with diamond or tungsten-carbide tipped bit.
It is also suitable for engineering geological subterranean water explorations as well as explorations of shallow layer oil and natural gas, and can be used to drill holes for ventilation and drainage of main gallery.Speacifications
