Depending on a couple of factors, the roll form tooling may be recut and dropped, or decreased, in diameter to eliminate wear. The first consideration is the vertical range of your roll form equipment. The vertical range (centers) is the distance between the top spindle and the bottom spindle, and on most machines it is adjustable (see Figure 1). A large vertical range allows for recutting of the roll, but a very small vertical range does not allow for diameter changes, which means the roll tooling must be replaced when it becomes worn.
