Frequently Asked Questions
Q: How does the automatic spring-loaded center punch work?
A: Simply press the hardened steel tip firmly against your workpiece surface. The internal spring compresses and then releases automatically at the top of its stroke, driving the tip into the material to create a clean, precise center mark — no hammer or mallet required.
Q: Can I adjust the striking force of the center punch?
A: Yes! The STONEGO center punch features an adjustable spring mechanism. Rotate the knurled top cap clockwise to increase force for harder materials like steel, or counter-clockwise to reduce force for more delicate surfaces like glass or thin wood.
Q: Is this center punch suitable for use on glass?
A: Yes. With the spring pressure set to a lower setting, this tool can score or mark glass surfaces effectively. It also doubles as an emergency window-breaking tool for vehicle safety situations, making it a practical multi-purpose addition to your car or toolkit.
Q: What is the total length of this center punch?
A: The STONEGO Automatic Center Punch measures 130mm (approximately 5.1 inches) in total length, making it compact enough to carry in a toolbox, glove compartment, or work vest pocket.
