What is the name of the hand-held miniature tool used to remove light corrosion from small avionic components?

The hand-held miniature tool used to remove light corrosion from small avionic components is known as a portable mini-abrasive unit. This tool is specifically designed for precision work, allowing technicians to effectively clean delicate surfaces without causing damage to the underlying material. Mini-abrasive units typically use a variety of non-metallic abrasives that can gently abrade the corroded area, ensuring that the integrity of the component is maintained while effectively addressing superficial corrosion issues.

Other tools mentioned, such as pneumatic sanders and mechanical polishers, may be more suited for larger surfaces or heavy-duty corroded areas, which can lead to potential over-processing or damage when used on more sensitive avionics components. A handheld grinder is generally more aggressive and is typically not used in the context of delicate avionics work. This makes the choice of a portable mini-abrasive unit ideal for managing light corrosion while preserving the precision required in avionic applications.
