Was core drilling a hole through a wall for a 25mm 4 core swa at work. Nothing to indicate that the cables were in the cavity. My pilot drill went right between them (through both walls).
The core drill then went through one side and didnt touch them either
Needless to say I carefully chiselled from the other side !
