The use of guide tubes in underground deep hole drilling result in straighter holes, which increases the drilling efficiency and reduces operating costs.
Thread: R32, T38, T45, T51, ST58, GT60, MT60, ST68 Diameter(mm): 46, 56, 65, 76, 87 Length(mm): 1220, 1525, 1830, 2280, 3050, 3660
Highlights 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.
