Kdma 22/5.5s Mining Motor-cutting-type Deep-hole Drill

Our range of KDMa 22/5.5S Mining Motor-Cutting-Type Deep-Hole Drill consists of the main frame, guide rail , drill pipe, drilling bit and hydraulic cylinder. Drill pipe sets up in guide rail; the end of drill pipe is hydraulic propulsion system. There is the motor and guide device in connection between the bit and drill pipe. The guide device mentioned above has guide bars paralleled to drill pipe axial outside the wall. There is space between the guide bars and guide device. Cutting edges are on both ends. Drill pipe axis with waterway. So problems like drilling difficulties and drill pipe breakage etc can be avoided. This also effectively improves the drilling precision and the maximum drilling depth. The space among the guide bars of the guide device can make the connection between motor and power easy and can be used as a mouth for scraps discharge so that slag discharge can be easily washed by high pressure water. The structure design is reasonable and of good practicability.
