Tool to assist in the removal of rivets

An arrangement for removing set metal rivets securing parts together and comprising:

• a rotatable drill having a predetermined length and being provided with a shank portion and a shoulder portion at one end thereof;
• a hollow compressible means adapted to surround the drill and to be compressed a predetermined distance;
• a member secured to an end of said compressible means and having an end adapted to engage the head of a set rivet, said engaging member being provided with a central aperture to permit passage of the drill therethrough as the compressible member is compressed by engagement with the shoulder portion of the drill to permit the rotatable drill to remove at least the central portion of the engaged drill head which extends above the outer surface of a secured part;
• and
• spacer means interposed between the shoulder portion of the drill and member for controlling the extension of the drill through the tool as the compressible member is compressed in drilling out the center of a set rivet.
