Applications
These integral drill rods are specifically designed for underground mining operations and small hole drilling applications. They are compatible with hand-held drill machines and small power rock drills including air leg rock drills and hand held rock drills. The rods significantly reduce impact energy expenses while improving drilling speed and efficiency.
Typical applications include drilling bore holes with diameters ranging from 30mm to 41mm. The quality of both the steel material and tungsten carbide components is critical for achieving optimal drilling performance.
Available in standard shank sizes H22x108mm and H19x109mm, with bit diameters ranging from 20-42mm. Custom lengths are available from 400mm to 6000mm to suit various operational requirements.
