ABSTRACT:
A rivet remover has a casing with a rivet contacting region that is shaped for emplacement on a rivet head and has an interior passage that extends to that region. A rotatable drill bit carrier rod is movable along the passage to cause the bit to cut into the rivet head. The carrier rod may extend out of the casing to enable use of an electric drill motor to drive the tool. The rivet contacting region is on a casing end member which may be disengaged and replaced with any of a series of other end members that have differing rivet contacting regions adapted for conforming with rivet heads of differing sizes and/or shapes. The preferred embodiment uses an ordinary twist drill bit and apertures in the casing side wall discharge shavings that are drawn into the casing by the bit. An adjustable stop limits penetration of the bit into rivets to avoid damaging of the riveted structure.
