Abstract

Utvidelses- og stabiliseringsverktøy for bruk i et borehull, omfattende et rørformet legeme (1) med et aksielt hulrom (2), og ved periferien spor som er innrettet med en åpning mot utsiden, et skjærebladelement (4) anbrakt i hver av de nevnte spor innrettet med i det minste to skjærebladarmer (5, 6) som er forskyvbare mellom en tilbaketrukket posisjon og en utstrakt posisjon, drivmidler (15) innrettet innvendig i det rørformede legeme, aksielt forskjøvet i forhold til skjærebladelementene, samt transmisjonsmidler som er i stand til å overføre bevegelsen av drivmidlene til de leddede skjærebladarmer, der disse skjærebladarmer, i den utstrakte posisjon, mellom seg og verktøyets rørformede legeme vil danne et rom (14) som er lukket i forhold til utsiden.
