Double Flare Upset Punch – 101857 Series – 220-035 | 0.125 TOD

This Double Flare Upset Punch drives the forming stroke that shapes 1/8″ (0.125″ decimal) tube, roughly 035 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 pipe end finishing lines avoid downtime. It is part of the 101857 series; compatible with DF tube end forming machines, and is a good fit for shops standardizing their pipe end finishing tooling.
