The top hammer tools are designed and produced to transmit high-frequency impact energy into the rock and minimize energy loss to improve the rock breaking rate, penetration rate, and productivity.
The piston of drill device directly impacts the shank and reach to the bit through rod by the form of stress wave to work on breaking rocks. Rockopia produces shank, rod, sleeve and bit etc.
Down the hole drilling is a kind of big diameter borehole drilling by extending the impacting power to the bottom of the hole. With high straightness, clean hole wall, good rigidity of drill pipe and hammer, without high axial thrust, no restriction of drilling depth and low cost, DTH drilling tools are widely used in open-pit mining.
