Cabezales de transmisión Shelby Tube

They enable reliable insertion and retrieval of Shelby tubes during undisturbed soil sampling in geotechnical investigations. Drive heads are manufactured from high-strength steel and help maintain sample integrity by distributing impact and pressure uniformly along the tube during drilling. The tight-fitting connection system seats firmly on the top of the tube, ensuring efficient transfer of torque and thrust forces from the drill rods. This feature minimizes deformation risks during sampling.
