Rig is two column vertical type, structure drilling direction is plummet. It consist of gasoline engine, gearbox, spindle, drill bit,upright,base lift structure, Cooling feed water pump and cooling walk institutions.

Drill machine helical gear made of alloy steel materials, tooth surface wear well after high frequency quenching. a v-belt wheel drive the synthetic diamond core bit rotates, lifting structure use advanced ball screw,easy and convenient.

Columns adopts thick wall seamless steel tube, after precision grinding hard chromium plating surface treatment,made the bit counterclockwise, move up and down to reach the goal of drilling or core.
