What is the function of a file in metalworking?

A file is a hand tool used in metalworking primarily for the purpose of removing small amounts of material to achieve a specific shape, smoothness, or finish on a workpiece. When working with metal, using a file allows for precise control over the amount of material being removed, which is essential for tasks that require accuracy, such as fitting parts together.

The ability to grind down metal slowly and evenly is what makes files particularly valuable in the metalworking process. This controlled action helps in refining surfaces, eliminating burrs, and achieving desired contours without excessive material loss.

While files can also contribute to activities such as flattening surfaces or creating edges, the most notable function is indeed the careful removal of material, ensuring that finer adjustments can be made efficiently. Therefore, this emphasis on the ability to remove small amounts of metal at a controlled speed reflects the specific strengths and applications of files within the metalworking trade.
