Frequently Asked Questions

Q: How does the automatic spring-loaded center punch work?

A: The center punch uses an internal spring-loaded mechanism. When you press the tip firmly against your workpiece, the spring compresses and then releases with a sharp, controlled impact — creating a precise indentation without needing a separate hammer. Simply position the tip and press down.

Q: Can this center punch be used on metal as well as wood?

A: Yes! The hardened steel tip is designed to mark a wide range of materials, including wood, metal, and plastic. It's ideal for spotting drill holes to prevent bit wander on any of these surfaces.

Q: Is the glass-breaking function safe to use in an emergency?

A: The glass-breaking tip is designed to shatter tempered glass (such as car side windows) with a focused impact point. It is intended for emergency situations where you need to exit a vehicle quickly. Always keep it in an accessible location in your vehicle or emergency kit.

Q: What size eyelets can this tool punch?

A: This center punch is suitable for standard eyelet punching in lightweight materials such as leather, canvas, and craft fabric. For best results, use it in conjunction with an appropriate eyelet setting tool and backing surface.
