HammerHead has introduced a pneumatic hammer rock drilling system capable of drilling 6.25-inch-diameter holes at penetration rates of up to 150 feet an hour. The new ROUGHNECK R500 turns any horizontal directional drill in the construction industry into a high-production rock drilling machine.
The system is a larger version of the ROUGHNECK R400 system introduced last year. The newest ROUGHNECK includes the R500 air hammer with heavy-duty, high-flow housing; 6.25-inch straight and offset bits, patent-pending pullback kit, control station/oiler and drill conversion kit.
