DTH drilling machine for blast-hole in quarry

The DTH drilling machine is used for drilling large diameter horizontal, vertical and slant holes during stone quarrying. This portable DTH drilling machine is necessary assistive equipment to two wire saw machine during the stone quarrying. The machine is controlled jointly by compressed air or electric motor and compressed air. And the pneumatic DTH drilling machines are high quality standard.

DTH drilling machine is used for hard rock blast-hole, slope-protection etc. projects. It is ideal tool in quarry project.

1. Low compressed-air consumption, high drilling efficiency, light in weight, easy operating and installing, etc.
2. The particular screwing and discharging mechanism of tube devices reduces the intensity of laber.
3. The portable drilling machine has the particular design for guiding drilling.
