Hollow Punch

grabcad

A set of 10-part hollow punches includes a marking stamp and nine interchangeable punch tools with diameters ranging from 2 to 10 mm. The non-standard metric threads on the punch tools fit into the marking stamp, which has a 13.5 mm diameter thread with a pitch of 1.35 mm. These threads are without clearance. The knurls have been newly defined and look more realistic than previous projects. Applications for this tool include punching holes for circular parts in materials like leather, felt, rubber, paper, or plastics but not metallic materials if the punching tool is not hardened. The model is available in STEP (.stp), Native files (.prt) and (.asm) formats for users of PTC Creo Parametric 2.0, with a verified (.stp) file opening.
