Abstract

En borrkrona (1) omfattar borrkronans (1) stomme (2) och på ett avstånd från borrkronans (1) ändyta upprymningsstålvingar (21) som rör sig utåt från flanken (6) till borrkronans (1) stomme (2). När borrkronan (1) roteras i den avsedda borrningsriktningen är upprymningsstålvingarna (21) anordnade att röra sig utåt från flanken (6) till borrkronans (1) stomme (2) och sträcka sig utanför borrkronans (1) stommes (2) största ytterdiameter för att vidga hålet som borras. När borrkronan (1) roteras i den motsatta riktningen är upprymningsstålvingarna (21) anordnade att återvända tillbaka innanför borrkronans (1) stommes (2) största ytterdiameter för att dra borrkronan (1) bort från hålet som borras.
