Pneumatical & Electrical DTH Quarry Drilling Machine

The DTH drilling machine is used for driling large diameter horizontal,vertical and slant holes during stone quarrying. It is necessary assistive equipment to wire saw machine during stone quarrying. The machine is controlled by compressed air motors. And the pneumatic Units are high quality standard. The machine, has the following. features: low compressed-air consumption, high drilling efficiency. light in weight, easy operating and installing etc. The particular screwing and discharging mechanism of the tube devices reduces the intensity of labor.And the machine has particular design for guiding drilling.
