The article changes with the case; it is shown in colour.
'Bohrloch' (drilled hole / borehole) consists of the verb stem 'Bohr-' from 'bohren' (to drill) and the noun 'Loch' (hole). The first part indicates how the hole was made.
Mit dieser Maschine können wir auch in Beton saubere Bohrlöcher herstellen.
With this machine, we can also make clean drilled holes in concrete.
In DIY work, people often talk about the 'Durchmesser des Bohrlochs' (diameter of the drilled hole) and the 'Tiefe des Bohrlochs' (depth of the drilled hole). Typical descriptions are 'zu eng' (too narrow), 'zu weit' (too wide), and 'zu flach' (too shallow), especially when a wall plug needs to fit inside.
Das Bohrloch ist zu weit, deshalb sitzt der Dübel nicht fest.
The drilled hole is too wide, so the wall plug doesn't fit securely.
When something goes into the opening, use 'in' with the accusative: 'ins Bohrloch' (into the drilled hole). For something already inside it, use 'in' with the dative: 'im Bohrloch' (in the drilled hole).
Drücke den Dübel vorsichtig ins Bohrloch.
Gently push the wall plug into the drilled hole.
Im Bohrloch ist noch Staub.
There is still dust in the drilled hole.
In technical reports about deep drilling, you will find the phrase 'ein Bohrloch verrohren' (to case a borehole). This involves installing pipes in the borehole to stabilize its walls.
Die Firma hat das Bohrloch mit Stahlrohren verrohrt.
The company cased the borehole with steel pipes.
