摘要： An extraction tool (20) for extracting spiral threaded inserts includes an elongated basic body (23, . . . , 26), on the one end of which an extracting tip (28) narrowing toward the front and intended for being inserted with a cutting action into the threaded insert to be extracted is provided, and on the other end of which a device (23) for turning the extraction tool (20) about the tool longitudinal axis is provided. In the case of such an extraction tool, extraction of the threaded inserts through inspection ports is made possible in a simple and reliable manner by virtue of the fact that at least a section of the extracting tip (28) has the shape of a steep-angle truncated pyramid (28.1).
