ABSTRACT:
A method and apparatus for extracting a test sample from a metal object. An annular portion of metal is removed from the metal object, such that an annular cavity surrounds a cylindrical sample of metal. A tool having a rigid elongated shaft is provided. The shaft has a longitudinal axis and a first end and a second end. The first end of the shaft has a cylindrical lower surface and a cylindrical upper surface which lie at a selected angle relative to one another such that the first end of the shaft is tapered. The first end of the shaft terminates in an arcuate edge. The arcuate edge of the tool first end is then inserted into the annular cavity surrounding and forcibly engaging the cylindrical sample. A longitudinally-directed force is then administered upon the second end of the tool until the sample is separated from the object.
