Rock drill extension rods, as the name suggests, are elongated tools designed to extend the reach of rock drills, enabling workers to bore deeper and more precisely into hard rock formations. These rods are typically fabricated from high-grade steel alloys to withstand the intense forces generated during the drilling process. Their resilience is further bolstered by thermal treatment procedures that ensure a balance between toughness and flexibility, preventing fractures under pressure.

  • The single needle lock stitch is achieved using a sewing machine equipped with a needle and a bobbin. The process begins when the needle pierces the fabric, carrying the upper thread down into the fabric layers. As the needle goes down, the bobbin, which is located underneath the fabric, rotates. The upper thread wraps around the bobbin thread, forming a stitch. When the needle pulls back up, the thread tightens, securing the stitch in place.
