  • Patent number: 5214831
    Abstract: A tool for extracting a helicoil from a threaded hole is provided. The tool includes a wedge member which is configured such that it is capable of wedging one end of the helicoil away from the threads. The tool is also equipped with a pair of jaws which engage the end of the helicoil once it is wedged away from the threads. The tool is then twisted in such a direction that the helicoil tends to be contracted toward its longitudinal axis. Continued turning of the tool in this manner results in extraction of the helicoil from the threaded hole. The tool may also be equipped with a forward cylindrical member for positioning the tool within the interior of the helicoil prior to engagement of the helicoil.
