hard rock mining Integral drill steel,Integral drill rod

Integral drill rod or integral drill steels, integral rods are used by hand held rock drill in granite and marble quarries, underground mining, for small blasting hole drilling.

It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 19mm to 41mm usually. Each rods use premium quality alloy steel and excellent quality tungsten carbide to assure high drilling performance.
