Pull and pinch metal extrusions, such as L-channels, so they fit precisely around contoured edges and frames. These tools shrink or compress curves as well as smooth ridges and dents without heating or welding.

With hardened rollers and precision-machined gears, these rolling mills stand up to heavy use. They’re often used to compress sheets to an uncommon gauge size, convert scrap metal into sheets or wire, or create different thicknesses in a single piece of metal without welding multiple pieces together. After several passes through the mill, you may need to anneal your metal to soften it and prevent cracking.
