H22 drill rod manufacturers believe that in drilling and blasting projects, due to the limitation of borehole diameter, the cross-sectional area of rock drilling tools is very small. However, under severe wear and corrosive media conditions, this slender rod needs to withstand the tensile, compressive, bending and torsion cyclic stresses imposed by high-frequency, high-impact power rock drilling tools.
