19mm Plug Hole Integral Steels

Plug hole integral steels, 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. Shank H22*108mm, H19*108mm, and standard hex. Bit diameters range 20-42mm, different lengths are available from 400mm to 6000mm usually. It can reduces the expense of impact energy, improves the drilling speed and efficience, also it can be used for drilling bore hole diameter form 19mm to 41mm usually. Each rods us premium quality alloy steel and excellent quality tungsten carbide to assure high drilling performance.
