Frequently Asked Questions
Q: Can the STONEGO Automatic Center Punch be used on materials other than metal?
A: Yes. While the automatic center punch excels at marking steel and other hard metals, it can also be used on wood, plastic, and similar solid materials. Adjust the spring pressure via the knurled top cap to suit the hardness of your material.
Q: How do I adjust the striking force of the spring-loaded center punch?
A: Simply rotate the knurled cap at the top of the punch clockwise to increase force or counter-clockwise to decrease it. This lets you fine-tune the depth of the center mark for different applications without needing any extra tools.
Q: Does this center punch require a hammer?
A: No hammer is needed. The automatic spring mechanism stores and releases energy internally with each downward press, creating a sharp center indent on its own — making one-handed operation easy and safe.
