HammerHead claims its Roughneck R500 rock drilling system can turn any horizontal directional drill in the construction industry into a rock drilling machine capable of drilling 6.25-in.-diameter holes at up to 150 ft. per hour. The larger version of the Roughneck R400 introduced last year includes the R500 air hammer with high-flow housing. 6.25-in. straight and offset bits, patent-pending pullback kit, control station/oiler, and drill conversion kit.
- Heavy-duty R500 housing permits directional drilling in varying rock conditions without chang of housings
- Larger bore diameter allows the hammer to send more air to the internal piston for faster, harder blows
- Integrated face-cleaning exhaust ports help prevent plugging of the hammer for reliable performance
- Patented check valve located in the bit eliminates ingestion of debris
- Integrated electronics give the operator control without leaving the operator’s station
- Control station uses the drill’s existing mud pump to deliver air, oil and fluids down hole
- Control stations can be installed with a tee and ball valve on the high-pressure side of the mud pump to direct airflow to the drilling-fluid supply line
