The punch force required to punch a piece of sheet metal can be estimated from the following equation: [4] F = 0.7 t L ( U T S ) {\displaystyle F=0.7tL(UTS)} Where t is the sheet metal thickness, L is the total length sheared (perimeter of the shape), and UTS is the ultimate tensile strength of the material.

If hard covers are desired, they must be punched as well. In bulk applications, a paper drilling machine may be used. Then the user chooses a spine size that will match the document.
