Features: The spring structure inside the center punch provides strong impact force for punching steel plates, wood plates, and breaking windows. The non-slip shell is durable. After pressing firmly, the impact is triggered accurately. The impact tip allows precise positioning and glass breaking on high-hardness metal. Description: Name: Automatic Center Punching Locator Usage: Align the positioning point with the target surface, hold the handle firmly, and press toward the punching direction. Once pressed back into the rod briefly, a strong spring rapidly ejects the punch to create a mark, eliminating the need for additional tools like a hammer. Simple and easy to use.
