Abstract
En borkrone for boring av et borehull i et objekt, idet borkronen har en senfral lengdeakse og omfatter et styreavsnitt (1) for boring av et styreboringsavsnitt av borehullet i objektet, et utvidelsesavsnitt (3) i en etterfølgende posisjon i forhold til styreavsnittet (1), idet utvidelsesavsnittets (3) skjærediameter (Du) er større enn styreavsnittets (1) skjærediameter (Dp), en forbindelsesaksel (4) som sfrekker seg mellom styreavsnittet (1) og utvidelsesavsnittet (3), og et stabiliseringsavsnitt (2) som er beliggende mellom styreavsnittet (1) og utvidelsesavsnittet (3), hvor stabiliseringsavsnittet (2) passer innenfor styreboringsavsnittet og er i stand til sideveis stabilisering av borkronen i forhold til objektet mens det tillater rotasjon av i det minste styreavsnittet (1) i forhold til objektet.
