Product Description

Backhammers
COP Backhammers -- Time and equipment savers!
Rock drilling is a demanding business and poor rock conditions are a fact. Being stuck in the hole can result in serious down time, loss of equipment and damage to the drill. Stuck in the hole problems can be eliminated by using an Atlas Copco COP Backhammers. The COP Backhammer fitted to a tube joint between the drill support and the rotation head provides backward hammering and vibration to free the stuck drill string.
Just as you insure you equipment, ensure your profits by incorporating an Atlas Copco COP Backhammer into you DTH string.
NOTE! The COP Backhammer comes in 3 1/2' API Reg threads in both ends


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.
