Integral drill rod, also called integral drill steels, are used on hand held rock drills in granite and marble quarries, mining, for small blasting hole. Shank H22*108mm, H19*108mm, and standard hex. Bit diameters range 20-56mm, different lengths are available from 400mm to 8000mm. It can reduces the expense of impact energy, improves the drilling speed, also it can be used for drilling bore hole diameter from 19mm to 56mm. Each rods use premium quality alloy steel and excellent quality tungsten carbide to assure high drilling performance. 1) Type: Chisel or Cross
