The use of guide tubes in underground deep hole drilling result in straighter holes, which increases the drilling efficiency and reduces operating costs.
Thread ends of the rods are made of quality materials and processed with heat treatment, which can reduce dents in thread ends and extend service life;
Risk of thread end breakage is reduced;
Less thread wear on the outer and inner sides of rod ends increases use efficiency and service life;
Tight tolerance of rods ensures safety, durability and high quality.
