ABSTRACT:
A punch for setting a rivet has features to prevent swelling of the rivet between the two members being secured together. The punch has an elongated, solid blow transmitting member with a blow receiving surface and a shank. A sleeve is slidingly carried by the shank and movable from a position protruding past the lower end of the shank. The sleeve has a sidewall with at least one elongated slot extending therethrough. A pin is secured in the shank and extends laterally outward from the shank into the slot to retain the sleeve. A spring urges the sleeve downwardly.
