DTH drill rods transmit compressed air, so as to power the hammers to perform drilling works.
Features Complete sizes for option, suitable for different types of DTH drilling system; The rods are made of cold-drawn steel with high manufacturing precision; Thread joint sturdily linked to the rod via friction welding; Nitriding process grants the thread joint good hardness, good wearing quality and thus long lifespan.
Applications Mining, quarrying, water well drilling, geothermal well drilling, foundation piling, etc.
