Woodward Fab Dimple Die Punch and Flare Tools Dimple die punch and flare tools by Woodward Fab create distinctive holes in sheet metal. They can be used with up to 16 gauge for mild steel and 14 gauge for aluminum. Starting with a small pilot hole and tightening the provided draw stud bolt using two wrenches， these tools will first punch the hole―then continue to form the flare as the two sides are brought together. Flaring the hole adds rigidity and stiffness to the panel and reduces weight， while adding a striking feature to any custom application. Order the flanging die outside diameters needed for your projects. Additional details:* Draw stud-style; use without a press* Creates a clean hole and produces a gentle flare* Heat-treated steel construction
