The HammerHead Roughneck R200 2-inch air hammer is the smallest pneumatic rock hammer in the line, and is designed for hydraulic directional drills between 7,000 and 10,000 pounds. It drills a 3.125-inch pilot hole.
The operator can electronically adjust air flow anywhere from open to closed for use in applications where soil conditions change abruptly. It can drill up to 150 feet per hour, and has a side-load high-flow housing.
The full system includes a hammer, offset and angled offset bits, patented pullback kit, control station/oiler with tethered electronic remote control, hydraulic breakout tooling, 2.5-inch universal high-flow housing, and a conversion kit specific to the drill.
