Back hammer for DTH drilling
In case of jamming of any drilling tool in the boring process, the backhammer will help you save time and money.
The backhammer may be mounted on the drill pipe joint between the borehole gripper and the swivel head, thus creating a combined effect of effective reverse impact and vibration.
Sturdy and reliable, the backhammer is composed of three components and a plastic housing which acts both as an exhaust emissions guider and a muffler. With regards to the maintenance, it's only necessary to kecp it clean and the linking section we protected when the backhammer is not in use.
