tunneln vs bohren
to drill / probe
'bohren' and 'tunneln' can both have to do with working through solid material using tools or machines. 'bohren' usually means making a hole, for example in wood, concrete, or a wall. 'tunneln' means building a tunnel through an obstacle, for example through a mountain or under a river. The words can be confused because material is removed in both cases. The difference is the size and purpose: drilling creates a hole; tunneling creates a route or passage.
tunneln
Für die neue Bahnstrecke tunneln die Arbeiter durch den Berg.
For the new railway line, the workers are tunneling through the mountain.
bohren
Vor dem Regal musste Paul zwei Löcher in die Wand bohren.
Before putting up the shelf, Paul had to drill two holes in the wall.
