100B(D) Light DTH Drill Rig


100B and 100D DTH drill rig is a kind of light and effective drill rig. It is cheaper and easier to be operated and repaired, especially to be used in stonework drilling, such as water and electricity project, construction of roads and national defense engineering. This machine can be applied for the rock hardness f=8-16 grade.

100B is pneumatic driven model and 100D is electric motor driven model, they both could be matched with low pressure and medium pressure air compressor.
