SPC Performance 3.0in. FLARED HOLE DIEOften called "dimple dies", flared hole dies are used in sheet metal fabrications to provide rigidity and strength to flat, unsupported panels. Due to the resulting high strength to weight ratio applications promoted by the use of this technique, flared holes are found in many aircraft and race vehicles designs. Beginning with comprehensive finite element analysis supported by extensive prototype testing, our Flared Hole Dies are engineered to provide
