Backhammer
In the event of jamming during the drilling process, the Backhammer reverse hammer saves you time and reduces costs. Installed between the rotary head and the drill string, it produces reverse percussion and vibration effects to resolve the jamming problem. The equipment is available from stock.
Made up of five parts — pistons, casing, chuck, base and side pin — the reverse hammer has a very simple structure that is easy to maintain: simply keep it clean and protect the connection area.
