Wall bush hammering is the most punishing finishing operation in second-fix work when carried out by hand. Bush hammer in hand, arms raised, vibrations accumulated over several hours: the result is irregular and the operator builds up chronic musculoskeletal disorders. Sept Tools offers two brushless mechanised solutions that industrialise this operation. The Mygale gantry set paired with the Petit Potam covers standard sites. The Gazellomur 3-in-1 combo goes further with productivity 4 to 6 times higher thanks to its natively built-in strain relief.

Your questions, answered
What is the difference between the wall set and the Gazellomur for bush hammering?
The wall set (Mygale gantry + Petit Potam) covers standard sites at 7 to 10 m²/h. The Gazellomur 3-in-1 combo reaches 42 to 63 m²/h on concrete thanks to its built-in power density and its native strain relief.
Why is the Gazellomur 4 to 6 times more productive?
The Gazellomur natively integrates the strain-relief gantry within its mechanical architecture. The operator does not have to carry the machine, the load transfer to the gantry is total. Coupled with the constant-torque brushless motor, the steady feed lets the pace be sustained without fatigue.
Does wall bush hammering damage the rebar?
No. Bush hammering acts on the surface, on the first few millimetres of concrete. Reinforcement remains intact as long as the operator respects the working depth recommended by the machine.
How is the Gazellomur Bouchardage cleaned?
The tool is IP65 sealed. Brush or low-pressure jet cleaning at end of shift is sufficient. Plates remove in one minute for thorough cleaning after long runs.
Can grinding and bush hammering be chained on the same job?
Yes, the Gazellomur is a 3-in-1 combo (grinding, bush hammering, planing). The operator changes the drum in less than two minutes without changing machine. Time savings and logistics simplification on multi-purpose sites.
