ABSTRACT:
A tool for removal of rivets includes three main sections--a tubular body section, a base, and a drive shaft assembly. The drive shaft assembly includes an upper portion to be received in the chuck of a rotational source of power and a lower portion to be received in the bore of the tubular body. An internally threaded drill receiving socket is disposed at a lower end of the lower portion of the drive shaft. The body section includes a coil spring for retracting the drill and a drill stop bushing for limiting the depth of penetration of the drill bit into the rivet. The base includes an upper disc and a larger diameter lower disc and three equally spaced tubular legs connect the upper disc to the lower disc. The bottom of the base includes a non-slip polymeric pad for contacting a work surface surrounding the rivet and stabilizing the cutting path of the drill.
