This is coin ring making tool I got off eBay. I is made just for punching a 1/2 inch hole into quarters. For this purpose it is perfect. I am able to punch though many quarters in a short period of time compared to the Harbor Freight punch and die kit. While both tools work, this one gets a perfectly centers hole every time.
Check out the video to see how it works.
