DESCRIPTION

Top hammer drilling is all about transmitting intensive impact energy into the rock with minimal loss of energy. With that in mind, we offer quality top hammer drilling tools for short hole system, production mining system and tunneling and ground support system. From handheld drill steels and bits, to a complete selection of rods, couplings and adaptors, we provide complete solutions for any drilling application.
