Direct Product Definition
An ISO 8020 Type F stepped piercing punch with an internal ejector.
The Universal Punch #575 is identified on the catalog product sheet as an ISO 8020 Type F round piercing punch for press tools used mainly in piercing and cutting perforations into sheet steel.
The Type F drawing combines a stepped shaft profile with an internal spring/ejector arrangement. Published catalog data identifies an m5 fit for d1, a j6 fit for the reduced d3 step, HSS construction, hardness ranges and the ordering dimensions required to configure the punch.

Application Selection
Use Type F when the tooling design requires stepped geometry and assisted blank ejection.
Selection should follow the component print, press-tool design, required working diameter and ejection requirement rather than series number alone.
02
Confirm the stepped geometry
Specify d1, d2, d3, T, t, l1 and l2. The published drawing identifies d1 as m5 and the reduced d3 step as j6.
