borierte

Borierte is the simple past tense form of the German verb borieren. Borieren is a technical term used mainly in mechanical engineering, metalworking, and related fields to describe the act of boring or drilling a hole with a view to achieving a precise diameter or finish. The past participle of the verb is boriert, and it is used with the auxiliary haben to form perfect tenses (for example, der Durchmesser wurde boriert).

In practice, borieren denotes a finishing or precision operation that follows an initial drilling. While bohren broadly means to drill a hole, borieren implies achieving tight tolerances and a specific bore diameter, sometimes by removing material more accurately with a boring tool or reamer. A typical workflow may involve initial drilling to a rough hole, followed by borieren to reach the final, specified dimension.

Usage and phrasing in German texts reflect its technical character. Examples: Er borierte das Loch auf 10,00 mm; Die Werkstücke wurden auf Ø12,0 mm boriert. The term is most common in engineering specifications, manufacturing instructions, and quality-control documentation. Outside strictly technical contexts, borieren is uncommon, and bohren is often used as a more general synonym.

Etymology is not part of everyday discussion in most sources, but borieren belongs to a family of German -ieren verbs formed from the noun or verb root related to boring. As a result, borierte functions as the narrative past form in sentences describing completed machining operations.
