Punch, Joggler & Flange Tools

An air punch drives a shaped die through sheet metal to form a clean hole or profile. Unlike a drill, it doesn't remove material as swarf — it displaces it, leaving a burr-free edge that won't snag gaskets or wiring. Flange tools bend a lip along a panel edge, creating a stiffener or a mating surface for rivets and fasteners. Jogglers offset one sheet relative to another so panels overlap flush — common in aircraft skin repair and box fabrication where you want a smooth exterior.

Throat depth decides how far in from the panel edge you can work. A shallow throat suits edge work; a deeper one reaches past flanges or into the centre of wide sheets. Check the maximum material thickness each tool will handle — mild steel gauge limits differ from aluminium or stainless, even at the same nominal thickness. Die sets are task-specific: round punches for cable grommets, square or slotted dies for louvre vents, radius dies for joggle joints. If you're working across several profiles, look for a tool that accepts interchangeable dies rather than buying a dedicated unit for each job.

Air consumption matters if you're running off a small compressor. A tool pulling 150 litres per minute will cycle slowly on a 50-litre tank, and you'll spend more time waiting than punching. Match the tool's CFM demand to your compressor's delivery at working pressure, not its peak displacement. Sealey air punch and flange tools are built for workshop or mobile service van use, with steel frames and replaceable wearing parts.
