Abstract

En slagborkrone for boring i en undergrunnsjordformasjon, hvor borkronen har en sentral langsgående akse og kan brukes ved å tilføre gjentakende aksiale hammerslag på borkronen i en retning med en komponent langs aksen og ved å tilføre en dreiebevegelse rundt aksen i forhold til jordformasjonen, idet borkronen omfatter en eller flere aksiale kuttere for hovedsakelig aksial kutting av undergrunnsjordforrnasjonen som svar på de aksiale slag, en eller flere skjærkuttere for hovedsakelig skjærkutting av undergrunnsjordformasjon som svar på dreiebevegelsen, idet det finnes en første skjærekutter av en eller flere skjærkuttere og hvor en eller flere av de aksiale kutterne er anordnet i forhold til minst den første skjærkutter for å gripe inn i undergrunnsjordformasjonen tidligere under et hammerslag enn minst den første skjærkutter.
