The product descriptionThe goal of drilling tools is the completion of rock drilling and drilling hole through transmitting the energy produced by the rock drill to rock. QIANRUI DRILL TOOLS designed and produced the new series MF drill rods aim at open air drill specially with the strict science and technology achievements and the perfecting production technology after collecting a lot of customer feedback of open air drills. New series of drill rods improve the speed of rock drilling with good transmitting of energy from drills to rock, stronger drill rods and the smaller losses of energy transmission. We have a whole set of mature technologies at these aspects such as smelting technology and facilities, machining process and facilities and heat treatment process and facilities.  We can produce the products perfectly they are general rods series and quick gods series with different length such as T38-3.66m general rods/quick rods and T45-3.66m general rods/quick rods and other rock drilling machines applied in different areas of ground and underground.1.
