ProDrill Integral Drill Steel 's raw material is 40SiMoCrNiMo=Atlas Z708. In the whole of China, only our local steel factory adopts this unique process (adding a layer cooper cushion) to produce this steel. Theoretically speaking, the steel of this process is more suitable for integral rods and taper rods, but in the later stage of processing, because the customer requires the shape of the shoulder of the integral rods to be close to the shape of Atlas.Under this case, the shoulder of the drill rods deformation will increase by 10%, which will cause the shank of the integral drill rods to break. We improved the process and kept the size of the shank below 33mm, which can increase the service life of the integral drill rods.
Rock drilling tools ProDrill provides a variety of integral drill steel and plug hole rods in a full range of lengths and steel hex diameters for all of your hand-held pneumatic drilling needs.
Integral drill rod\'s shank sizes 82.5 mm*22mm(3 1/4”*7/8”), 108mm*22mm(4 1/4”*7/8”), 108mm*25mm(4 1/4”*1”), 159,*25mm(6 1/4”*1). Lengths: 400mm to 6400mm(1’4”-21’). Head diameters: 27mm to 40mm.
Integral drill rod, another name called integral drill steels, integral rods are used by hand held rock drill in granite and marble quarries, underground mining, for small blasting hole drilling shank H22x108mm, H19x108mm, and standard hex. Bit diameters include 20-42mm,different lengths are available from 400mm to 6000mm usually.
It can reduce 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. Each rods use premium quality alloy steel and excellent quality tungsten carbide to assure.
