In case of jamming of any driling tool during the boring process, the back hammer will help you save time and money.
The back hammer 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 back hammer is composed of three components and a plastic housing which acts both as an exhaust emission guider and a muftler. With regards to the maintenance, It is only necessary to keep it clean and the linking section well protected when the back hammer is not working.
