The Roughneck R500 pneumatic hammer rock drilling system is capable of drilling 6.25-inch-diameter holes at penetration rates of up to 150 feet an hour, the company says.

It 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. The heavy-duty housing permits directional drilling in varying rock conditions without changing out the housing.

The larger bore diameter of the housing allows the hammer to send more air to the internal piston for maximum efficiency, resulting in faster and harder blows, according to HammerHead. A patented offset rock bit design provides precise steering, allowing the operator to navigate a wide variety of ground conditions.
