the difference between an automatic center punch and a hammer/nail
In: Engineering
Technically? Alot. If your question is there ultimately any difference in functionality, then not so much. If you’re careful, you can start a guide dimple with a hammer and nail easily. The advantage of the auto punch is that it’s smaller, lightweight, and since it uses the force of the internal spring for the punch, a hammer isn’t needed. This all means that you can theoretically do more punches faster and more accurately, and use less energy to do it.
