Eliminating Surface Galling
High-quality radius tools feature highly polished or specially treated forming surfaces. This smooth finish, combined with the wider contact area, minimizes sharp friction points compared to standard V-dies. This is particularly advantageous for preventing galling (material transfer) when working with sticky metals like aluminum or copper. The result is a cleaner, smoother surface finish on the inner bend, reducing the need for post-processing and surface touch-ups.
