Gooseneck Punch

A gooseneck punch features a curved or stepped body profile that creates clearance behind the punch tip, allowing the operator to form deep flanges and return bends without the previously formed material crashing into the ram or machine frame. This specialized tooling is indispensable for box forming operations where three sides have already been bent up and the fourth bend must clear those existing flanges. The offset geometry comes in various depths and angles to accommodate different flange heights and part geometries.

Without gooseneck punches, many common sheet metal parts, like deep channel sections, U-shapes, and four-sided enclosures for NEMA enclosures, would be impossible to produce on a standard press brake. Shops typically maintain a range of gooseneck profiles in their tooling library to handle the variety of part geometries they encounter in production.
