| Abstract: | QINGLONG", "JINLONG ", "PEILONG" brand cemented tungsten carbide integral drill rods made in the Huaxia ( Xianning) , Jinlong (Wuxue ) , Donghu ( Wuhan ) Rock Drill and Tool Companies, first time put on the market in quantity as the newest product of rock drilling rod in 1987, are widely used in internal-combustion, motor driven, pneumatic, hydraulic rock drill machine to drill rock with lashing way. Of integral drill rods, the bit has the size from 24 to 50mm in diameter, the turret shank diameter has B19, B22, B25, B28 and B32mm, the effective length has 400 to 6000mm. The character of rock and the direction of hole are not limited. This series products reflect the newest achieve-ment of minor diameter cemented tungsten carbide drill rod technology, with re-markable social and economic benefit, and have tremendous market of excavating industry field both at home and abroad. To popularize using the integral drill rods will result in third time renewal and change of the minor diameter drill rod in China, and strongly promote the progress of technique in excavating industry. |
