Automatic Center Punch: The automatic center punch feature ensures precise and accurate drilling, making it easier to achieve professional-looking results. Spring Type: The spring type design allows for easy and smooth operation, reducing the effort needed to use the tool. The spring structure inside the center punch can provide a strong impact force to complete the work of punching steel plates, wood plates, broken windows, etc. Usage: Align the positioning point with a heavy head, firmly hold the handle and press it towards the direction of the punch. After the punch is pressed back into the rod for a short period, a strong spring will vigorously eject the punch, creating a pit for the dots, without the need to cooperate with tools such as a hammer, which is simple and easy to use.
