Abstract: A bit usable in combination with a rotatory driver, such as a drill, for extracting a remnant of a cut-off pipe from a pipe socket. The bit comprises a forward portion which is a pilot to keep the bit centered in the remnant and thereby centered in the pipe socket, a forward-facing ring cutter whose inner and outer diameters generally match the inner and outer diameters of the pipe remnant being extracted, said ring cutter being operable to cut and/or scrape the remnant edgewise from the socket, and a forward facing ring scraper operable to stop the bit from excessive penetration into the pipe socket and operable to scrape bonding material remnants from the end face of the pipe coupling.
