Review: Looking for a Self Centering Punch Set, Just buy this one - The coin ring punch set is of good quality and functions well. The self centering die works well with all size coins and function as advertised. The only gripe would to be make the threads on the die a little bigger. The set I received came with two 3/8 inch punches and I did not get the 1/4 inch punch. I reached out to the seller and was told they are sending me a 1/4 inch punch but have not received it yet. Now for the price compared to the other self centering dies and punch sets, you get a hell of a deal. Check out Jason's Works price and you will be glad to pay this price. I would definitely recommend this product and would have given it 5 stars but I did not receive my 1/4 inch punch yet. Update, I received my 1/4 inch punch today. 31 March 2020. (5 STARS NOW) Review: MUST have for Coin Ring making - The coin ring hole punch shipped out quick and arrived on time. Packaged very well. I have been using a different brand for a while now. After seeing this style, I have been wanting to try it but couldn't see wasting the money on something we already had and works. I ended up with several coins that no spacer would work and it was going to be more trouble to find or make spacers to fit them. So We decided to buy the auto self centering coin hole punch. After getting and opening the box, it looks really nice. It seems very well made. We have only used it a few times but it works as it should without any problems. Honestly should have purchased it a long LONG time ago. Huge time saver over making spacer washers for every new or different coin. We both would buy again and highly recommend ## Features - ✔ Self-Centering Precision Design Domed, threaded lid automatically centers coins for accurate, consistent punch-outs—no spacers or adjustments needed. - ✔ Wide Coin Compatibility Designed to accommodate coins ranging from 1" (24mm) to 2" (50mm), including U.S. quarters and larger collectible coins. - ✔ Heavy-Duty Tool Steel Construction Crafted from heat-treated tool steel and alloy steel for exceptional strength, durability, and long-lasting performance. - ✔ Five Precision Punch Sizes Included Includes 1/4", 3/8", 1/2", 5/8", and 3/4" punches with updated die clearance for smooth, clean cuts. - ✔ Made in the USA – Beginner to Pro Ready Proudly manufactured in the USA and suitable for both novice and professional coin ring makers.

The increased clearance in the parts could lead to the punch getting stuck and you will definitely have more deformation than normal in the parts. There will be a big burr to trim if it goes ok. **Q: What is the smallest size (diameter) coin that can be used?** A: This is great punch and it will do Us Dimes with smallest punches **Q: Can i use a hammer with this?** A: You could but by hammering may misshape the end ,thus taking away the ability to flip the coin and punch over to tap the coin off of the punch. I use a 150.00 press. Well worth the investment, it makes ring production fun and not a chore, which is how it should be... **Q: Hard to get coin of after punching, any solutions?** A: I found using a little oil before you punch it helps and you might have to spray it again after as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Looking for a Self Centering Punch Set, Just buy this one *by A***R on March 25, 2020* The coin ring punch set is of good quality and functions well.

The interior taper holds the coins solid with no movement. The punch is clean and centered perfectly. I have almost every tool that this company makes. I've only had 1 issue and it was resolved in only a few days. I'm hoping to see more tools come out of their shop. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/158797380-big-self-centering-coin-ring-punch-set-no-spacers-needed](https://www.desertcart.co.uk/products/158797380-big-self-centering-coin-ring-punch-set-no-spacers-needed) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-24*
