Product Introduction

Top hammer drilling tools presents that the high-frequency piston strikes on the shank adapter generate significant impact energy, which is transmitted as stress waves through the rods to the drill bits, effectively breaking rock. This system achieves high energy densities of 200-400 J per impact while simultaneously completing rotary cutting. It has the advantages of strong penetration and large single rock-breaking volumes in hard rock, making them adaptable to complex working conditions in underground mining, open-pit operations, construction, and more. JSI offers the whole top hammer drilling string encompassing drilling bits, rods, shanks and couplings, which stably achieves high working efficiency and sustainable productivity in various drilling applications from soft to extremely rock conditions.
