Once you have punched a hole in your bodywork, you can make the panel stifferr than it was before and a heck of a lot more attractive, by using a dimple die of the correct size. The bend reinforces the panel and by using a punch and the die several times across a pnael you can both lighten and strengthen it whilst making it look like a racecar! Set the Die each side of the panel centred on the existing hole and then clamp together with a nut and bolt or use a hydraulic press.
The size stated is to match the HOLE size, so the dimple is formed larger.
Use our sheet metal punches if required to create the initial hole.
