• Chamfer — A specialized technical term borrowed via Germano-Austrian influence into professional or industrial dialects in the western and central regions, denoting a chamfer, bevel, or guiding groove executed on the edge of a metallic workpiece or a carpentry element. This structural detail has the geometric role of facilitating assembly, eliminating dangerous sharp edges, and ensuring the perfect sliding joint of component elements within a high-precision technical assembly.
• Reaming — The act of reaming or boring and its result; a technological machining process of internal cylindrical or conical surfaces, executed to enlarge the diameter of an existing hole and to ensure extremely high dimensional precision and minimal surface roughness. This process is essential in machine manufacturing for calibrating cylinders, bearings, and bushings.
• Reamer — A multi-edged cutting tool, featuring multiple longitudinal or helical cutting edges, used in metalworking for the fine finishing and exact calibration of holes previously made with a drill bit. This instrument ensures high dimensional precision (at a micron level) and superior inner surface smoothness, being indispensable in building engines, bearing housings, and aerospace components.
• Boring out — The act of boring out or reaming and its result; an informal or regional term equivalent to 'alezare', describing the industrial or artisan process of enlarging and calibrating an internal cylindrical cavity. Although it is avoided in academic technical manuals in favor of the literary noun 'alezare', the word is widely understood and used in metalworking and mechanical repair shops in Romania.
• Bored out — An informal or technical jargon variant for the adjective 'alezat'; regarding a cylindrical hole, an engine cylinder, or a tubular component that has undergone the process of internal enlargement, calibration, and finishing by cutting. The term is predominantly used in direct communication between auto mechanics, turners, and clients in repair shops, designating a part that is finished and brought to the desired repair dimensions.
• Large copper piece — Augmentative form of the noun 'aramă' or a rare adjective used in popular language to designate a huge, heavy, or thick object made of copper; it can also describe a coarse variant of unprocessed ore or an extremely intense, saturated chromatic shade resembling dense copper oxide.
