Traditional driller with electric rotation and hydraulic feeding system by means chromate steel double guide. Specifically designed to make the diamond wire guiding holes on marble and soft stones, the HDM is a sturdy and easy to use machine, studied for the heavy work of the quarry in the safest conditions.
The new hdm 635 drilling machine is designed to make the intersecting holes of 76 / 90 mm in diameter, where to pass the diamond wire in quarries of marble and granite. The drilling is made by a down-thehole hammer. The rotation and the advancement movements of the drilling are made possible via hydraulic motors.
Pneumatic drillers down-the-hole hammer system, designed to make the guiding holes for diamond wire. featured by high penetration speed, lightness and ease of use, they can hole vertical, horizontal and on any directions with 76/90 mm cylindrical rods. it is possible to dismantle the machines into different parts, for easier transportation and movement, especially in rough areas.
