Abstract

Et boreverktøy (10) inkorporerer første og andre ender, et skaft (13, 90) som strekker seg mellom endene. Den første ende har en borkrone (15) for å penetrere fjell. Borkronen og skaftet har komplementære gjenger. Borkronen og skaftet omfatter et middel (82, 83) for stopp av relativ rotasjon som sørger for at borkronen forblir løs under boring i en første retning. Oppfinnelsen vedrører videre en selvborende fjellbolt (10), en borkrone (15), et borskaft (13, 90) og skaftkopling (94), en forankringsanordning (23), og i for seg en endekopling (95).A drilling tool (10) incorporates first and second ends, a shaft (13, 90) extending between the ends. The first end has a drill bit (15) for penetrating rock. The drill bit and shaft have complementary threads. The drill bit and shaft comprise means (82, 83) for stopping relative rotation which ensures that the drill bit remains loose during drilling in a first direction. The invention further relates to a self-drilling mounting bolt (10), a drill bit (15), a drill shaft (13, 90) and shaft coupling (94), an anchoring device (23), and in itself an end coupling (95).
