DTH Back Hammer
The Eagle Back Hammer is designed for backward hammering and vibration. When the drill string or DTH hammer is stuck in the hole, you can pull it out very easily with our back hammer.
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.
In case of jamming of any drilling tool in the boring process, the backhammer will help you save time and money.
