These high quality dimple dies are used to improve the strength and appearance of a panel and will flange an existing hole in sheet metal up to 3 mm thick. They work great in a hydraulic press. Precision machined from hardened tool steel for years of use and each dimple die has a through hole drilled into both the male and female dies so they can be used in a few different ways.
The first method is they can be used in any H frame hydraulic press where the material you are dimpling is small enough to fit between the vertical frame rails of the press. Simply drill the appropriate size hole using an industry stand hole saw, then insert the male and female dies to the correct orientation then using the hydraulic cylinder, press the dimple dies down to flare the metal.
The second method is they can be bolted together using a standard grade 8 bolt M10, M12, M16 or M20 depending upon which dimple die size you have. This method is ideal for
