Wear Resistant Rock Drill Rods 20 - 42mm Diameter For Underground Mining
Characteristics
Integral drill rods are ideal in small hole drilling, all integral drill rods consist of hex. rods with integrated cemented carbide chisel-shaped bit heads. With the same steels as and the best carbides made in China, we are supplying different lengths of integral drill rods with different head diameters:
Shank sizes: Hex. 19mm, Hex. 22mm;
Head diameters: 26mm ~ 42mm;
Effective lengths: 400mm ~ 7000mm;
Ensure good drilling life by using superior tungsten carbide.
Stale and mature welding technology ensure good quality of rods
Integrate heat treatment ensure rod quality
Very cost-effective

Integral drill steels / rods are used by a hand held drill machine in underground mining and for small hole drilling, equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc. It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 30mm to 41mm usually. Regarding Integral drill steels,the quality of a steel material and a tungsten carbide is very important to get good drilling performance.
Shank H22x108mm, H19x109mm, standard hex. Bit diameters include 20-42mm, According to different application, different lengths are available from 400mm to 6000mm usually.
