Tonnage: Use the following formula to calculate the tonnage required to punch a round hole in mild steel: Punch diameter x Material Thickness x 80 = Tons of pressure required. Example: to punch a 1/2" hole through 1/4" thick mild steel 0.500 x 0.250 x 80 = 10 tons required. Use the following formula to calculate the approximate tonnage required to punch a shaped hole in mild steel:
