How do they Work?

With your shop press:

1. Make a hole saw hole of a matching Die size, taking care to de-burr the edges of the hole. Next, after having lightly oiled both Die contact surfaces, insert the top Die ( male end) into the sheet hole then into bottom Die (female end) thereby sandwiching the sheet between the two.
2. Set the assembly onto a flat surface in a shop press and apply gentle pressure until  both dies lay firmly against the surface sheet.
3. Lastly remove the Dies from the hole and a dimpled edge should now have been applied. Be careful not to apply excessive force or you may ( print ) the shape of the Die into your project!

With your existing hydraulic draw mandrel bolt :

1. Make a punched hole of a matching Die size, taking care to de-burr the edges of the hole.
2. After having lightly oiled both Die contact surfaces, insert the top Die ( male end) into the sheet hole, then into bottom Die (female end) thereby sandwiching the sheet between the two.
3. Insert your draw mandrel bolt through the top Die (male) and screw on the threaded bottom Die (female) end onto the bolt.
4. Draw the dies together until both dies lay firmly against the sheet.
5. Lastly, remove the Dies from the hole and a dimpled edge should now have been applied. Be careful not to apply excessive force or you may ( print ) the shape of the Die into your project!

Note: Many hobbyists will not have access to a shop press, and some projects will not leave the space            needed to use a press. For this reason, there is a threaded hole to bolt the Dies to a hydraulic Punch Driver or a standard bolt with a washers under both head and nut. ( oil is your friend here too) Washers will limit the scoring to the Dies. As with a press, draw both Dies together until they lay firmly against the sheet surface to apply the dimple.
