I'll tell my story. A hammer drill was bought for the construction of my house, I didn’t work often, I build with my own hands and slowly. Before this model, there was a puncher 25103, I gave it to a friend for a while, he managed to drop it from the second floor, the quality of the punch was super, he hammered, drilled, worked and worked. Bought this one. the operation was neat, cleaning after each use. And on you in a month the blow was gone. Took it to the service. Done. Three months later…
