  • Rivet removal tool and method
    Patent number: 7028380
    Abstract: A device and method of removing a rivet which has been installed on a work piece. The method includes clamping a hand held device having springs onto the work piece, engaging a drill with a drill bit of the hand held device, the springs applying a pre-load force to the drill bit, operating the drill, thereby causing the springs to apply an increased load force to the drill bit and causing the drill bit to drill into a button of the rivet, unclamping and removing the hand held device from the work piece, and using a compression tool to remove the rivet from the work piece. The compression tool includes a push out portion configured to push out the rivet, and a recess is disposed generally opposite the push out portion for catching the rivet as the rivet is pushed out.
