What is a Peen? - Definition, Uses, and Types

Peen is a tool used in metalworking to shape and form metal. It is typically a small, handheld tool with a pointed end that is used to punch holes or create indents in metal. The peen can be made of various materials, such as steel or carbide, and may have different shapes or sizes depending on the specific application.

In addition to punching holes, a peen can also be used to flatten or spread metal, creating a flat surface or a specific shape. This tool is commonly used in industries such as automotive, aerospace, and construction, where metalworking is a critical part of the manufacturing process.

The word "peen" comes from the Old English word "penn," which means "point" or "tip." It is related to the German word "Pfennig," which means "penny," and the Dutch word "Penning," which means "coin." Over time, the spelling of the word has evolved to "peen," which is now commonly used in metalworking and other industries.
