Abstract: A tool for extracting threaded inserts from threaded holes. The tool includes a drive shaft and one or more blades extending from the drive shaft at its insertion end. Upon insertion of the tool into a hole containing a threaded insert, the blades cut grooves into the top coil of the insert. The tool is configured such that the blades have an outer radius greater than the inner radius of the threaded insert but less than the inner radius of the parent threads. By rotating the tool, the user may then exert pressure against the sides of these grooves and rotate the insert out of the hole. In a preferred embodiment, the tool also includes a guide shaft at the insertion end of the tool, for aligning the tool in the hole and reducing the risk of contact between a blade and the parent threads. The engagement end of the drive shaft, located opposite the insertion end, may be configured to engage a drive mechanism.
