Rotary Dent Hammer

1 surface with elastic-rotating spiral contour 42 mm Ø and 1 smooth surface 31.5 mm Ø. For material thicknesses from 0.2 to 1.0 mm. The specially designed clamping head of the hammer converts the striking motion into a rotating motion, which tensions the material evenly through the fan-shaped surface of the hammer, ensuring that neither the material properties nor the material thickness are altered.
