läbiauguline

Läbiauguline is an Estonian adjective used primarily in technical and engineering contexts to describe a hole or a feature that passes completely through a material, from one face to the opposite face. The word is formed from läbi- (through) + auk (hole) with the adjectival suffix -line, signaling a property.

Usage: In engineering drawings, products and specifications, a läbiauguline hole indicates that the hole extends through the entire thickness of the part, as opposed to a blind hole that ends within the material. This has implications for manufacturing processes, finishes on both sides, and for accommodating fasteners, pins, or cables. The term can describe components, plates, housings, or assemblies with through-holes.

Related terms: While primarily a technical descriptor in Estonian, the concept corresponds to "through-hole" in English and to "durchgangsloch" in German; in electronics, through-hole mounting is a common category describing components whose leads pass through printed circuit boards.

Notes: The term is relatively specialized and most common in technical glossaries, manuals, and engineering documentation. In everyday Estonian, other words may be used depending on the context, such as simply 'auk' (hole) or 'läbivahe' for through passages, but läbiauguline conveys the through-through-hole property succinctly.
