This Double Flare Upset Punch is sized to 7/16″ (0.438″ decimal) tube, roughly 042 wall thickness, and produces the forming stroke needed for a proper double flare or upset end. Because it contacts the tube directly, punch condition has a direct effect on flare consistency and finish quality. It fits standard double-flare tooling setups used across end finisher shops. It is part of the 101422 series; compatible with DF tube end forming machines, and is a good fit for shops standardizing their end finisher tooling.
