The struggle is real when trying to use a standard punch and die set to punch a hole close to the web on a piece of angle iron, as it restricts just how close you can get to the edge. Punching close to the web shouldn't be a struggle. It's not when you use an offset die. By using an offset die you are able to get within 1/4" of the web.
Standard vs. Offset
|Standard Die||Offset Die|
A standard die(left) is arranged for the punch to clear in the center of the die and is mostly used to punch holes in the middle of material. An offset die(right) is arranged for the punch to clear close to the edge of the die which makes it easier to punch close to the *web of the angle. *Web- where the two edges meet or the vertex of the two legs.
Offset dies are just another way to make your punch station more versatile. Depending on the way your products are engineered, you may need to punch holes closer to the web than a standard die will allow. We may not refer to offset dies as “standard,” but lucky for you we always keep them in stock for Scotchman ironworker owners.
A common misconception is there are offset punches and dies. This is not the case, it is ONLY the die that is offset from center. The punch always stays in the same place. So, your favorite 9/16" punch is easily converted, to punch close to the web, with a purchase of an offset die of the same size.
