Long Hole Drilling

Long hole drilling rods are available in male-male and male-female options. Drilling with the minimum possible hole deviation is important for more consistent fragmentation, increased efficiency, and reduced operational costs. The male-male tunnelling / drifting rods are available in numerous design configurations are available for tunnelling /drifting hex or round cross sections (25H, 28H, 32H, 32R, 35H, 39R) in thread size up to R38 / R32 in various lengths up 21 ft (6.4m). The male-female design configuration eliminates the need for a separate coupling, resulting in fewer threaded connections, reduced hole deviation, and faster additions/removals to the drill string. Long hole rods are available in a wide range of diameters and threads with lengths.
