For high-production flanging operations, the F160-F161 or F162-F163 set is recommended. These dies hold the sheet flat while wiping a 90 degree flange either up or down. Back gauging can be easily fitted to the F160-F161 set, although the sheet will move approximately 1/2" down with the spring pad. The sheet does not move down when using die set F162-F163; however, front gauging is best suited for this operation. Maximum capacity recommended for the illustrated dies is 16 gauge, although heavier construction will allow forming up to 12 gauge.
