Abstract

En borkrone (11) for fastsetting på en langstrakt borestang (10), hvor borkronen (11) inkluderer anordninger for fastsetting på en ende av borestangen, og en fremre ende som definerer et par diametralt motsatte slisser (16, 17) som åpner seg aksialt for mottak av en del av en borespiss (18) som rager aksialt ut av slissene (16, 17). Borespissen (18) er fast sikret inne i hver av slisse ne (16, 17). Videre omfatter en borestang eller en selvborende takbolt den ovennevnte borkrone (11).
