Overview
At 0.19 ounces, the Starrett 18A is a small hand punch from a brand known for precision measuring and marking tools, listed under Tools, Punches.
At under a quarter ounce, the 18A is a light hand tool rather than a heavy-duty pin punch, consistent with Starrett's reputation for precision instruments. The listing does not specify tip diameter, overall length or whether it is a center, prick or transfer punch, so matching it to a specific marking job needs a closer look at the product page.

Who it's for
