This 5¼\" spring-loaded auto center punch delivers a sharp, consistent strike with nothing more than firm downward pressure — no mallet required. Built from hardened and ground alloy steel with a well-tempered center point, it is designed for long service life and reliable performance at the bench.\u003c\/p\u003e\n\u003cp\u003eAt approximately 2 oz and a full 5¼\" in length, this is a larger, heavier center punch than standard jeweler's models.
