Abstract
A shaft, a factory head, and a conical recess form a rivet. The shaft is cylindrical and includes a diameter, a first end, and a second end, the second end having a deformable portion to form a shop head. The factory head is connected to the first end of the shaft and has a diameter greater than the diameter of the shaft. The conical recess is preformed in the factory head coaxial with the shaft and narrows while extending into the factory head towards the shaft. The conical recess has an angle between 100 degrees and 135 degrees and a depth between 0.0254 centimeters and 0.1016 centimeters.

9. A method for removing a rivet that connects at least two pieces of material, comprising the steps of:
-
identifying a rivet to be removed, wherein the rivet comprises a factory head, a shaft that is cylindrical and attached to the factory head, a conical recess preformed in the factory head and coaxial with the shaft, the conical recess narrowing while extending into the factory head towards the shaft and having an angle between 100 degrees and 135 degrees and a depth between 0.0254 centimeters and 0.1016 centimeters; aligning a central axis of a drill bit with a central axis of the shaft by inserting an angled tip of the drill bit into the conical recess, wherein the drill bit has a diameter no larger than a diameter of the shaft; and forwardly moving and rotating the drill bit against the conical recess until the factory head is disconnected from the shaft. - View Dependent Claims (10, 11, 12, 13, 14, 15)
