Overview
The Klein 66344 is a punch weighing 12 ounces, built for one-handed marking or driving work. Klein Tools is a long-running trade brand, and this listing shows a single piece rather than a multi-tool set.
Nothing in the title or attributes contradicts the Punches category, so it's taken at face value here. The listing does not include a tip diameter or material, so buyers with a specific pin or hole size in mind should confirm the exact spec against Klein's own documentation before ordering.
