What is the primary use of a bar folder in metalworking?

The primary use of a bar folder in metalworking is to make bends or folds along the edges of sheets of metal. This tool is specifically designed for creating precise bends, typically at right angles, in sheet metal, which is essential for many fabrication processes. When working with metal sheets, achieving exact folds is critical for ensuring the structural integrity and fit of metal components in various applications, such as brackets, enclosures, and other assemblies.

The bar folder facilitates this process by allowing the operator to place a sheet of metal in position and then use a lever mechanism to apply pressure, resulting in a clean and accurate bend. This capability is crucial in metalworking, where precision can significantly affect the functionality and appearance of the final product.
