Pneumatic DTH Drilling Rig

Pneumatic DTH borehole drilling machine is widely used in mines,transportations,defense,water conservancy,rock engineer,especiaaly rugged terrain. Down the hole drilling machine   has the advantages of single power, simple structure, convenient operation, short auxiliary time, light weight and low use cost. Applicable to all kinds of open pit mining, hydropower, railway, highway engineering, drilling holes and rock drilling ore with various modeling holes. In the range of rock hardness coefficient f=8~16, high rock drilling speed can be obtained. It is your good partner to improve your efficiency. DTH drilling rigs ensure that the borehole is drilled in the range of 45° to 75° by adjusting the pins of the strut assembly.  DTH drilling rig 1.Hot sales dth drill rig 2.
