Top Hammer Bits

Top hammer drilling is all about transmitting intense impact energy into the rock being drilled with minimal loss of energy. Thus the process of drilling small diameter holes by top hammering imposes much strain on the drilling tools and equipment.

HEMCO top hammer bits and drill rods are manufactured to the highest standards using premium grade materials to give maximum meterage of drilling even in very hard rock formations.
