perfurar

Perfurar is a Portuguese verb that means to create a hole or opening in a surface or solid by drilling, punching, or piercing. It can describe both intentional actions, such as drilling a hole, and accidental ones, such as an injury that penetrates tissue. The related noun perfuração denotes the act or result of perforating.

In technical and industrial contexts, per­fu­r­ar is used for processes that involve making holes through materials such as metal, wood, concrete, or rock. It is common in construction, manufacturing, mining, and petroleum activities, for example in drilling wells or taking core samples. Equipment such as perfuradoras (drilling machines) and brocas (drill bits) are employed to perform perforation tasks with specified dimensions and tolerances.

In medicine and biology, perforation refers to the creation of a hole through a tissue or organ. This can occur as an intentional procedure—such as surgical perforation of membranes—or as an adverse event, such as intestinal perforation, which may constitute a medical emergency depending on the location and severity. The term is used to describe both the act of making the opening and the resulting condition or injury.

Perforation processes are typically governed by safety, engineering, and health standards to control hole size, placement, and the risk of leaks, contamination, or structural failure. In everyday language, perforar can be used to describe making holes in various objects, from walls to pipes, reflecting the general meaning of creating an opening through a barrier.
