Friction welded drill rods are used for vertical and directional (or horizontal) drilling, with various applica-tions, starting from ground consolidation and pile foundation, through geognostic inspections, geothermal applications, to oil - and any subterranean fluids search, including artesian wells and no-dig drilling. The con-stant research and empowerment of the production and process control of drilling rods as well as of the accessories composing or completing a "drill string" are the basis of our constant evolution.       Link utili:   Drilling Tools         Bellino Srl manufactures friction welded drill rods plain end and forged as well, augers, casings and subs of different diameters.
