Double Flare Upset Punch – 101422 Series – 620-032 | 0.375 TOD

This Double Flare Upset Punch drives the forming stroke that shapes 3/8″ (0.375″ decimal) tube, roughly 032 wall thickness, into an upset or double-flare profile. It is matched to its companion die, and the two work together to fold or thicken the tube end before the final flare is set. Wear on this punch shows up as inconsistent flare depth, so keeping a spare on hand helps tube end finishing lines avoid downtime. It is part of the 101422 series; compatible with DF tube end forming machines, and is a good fit for shops standardizing their tube end forming tooling.
