## Questions & Answers

**Q: Question for the seller: Can I substitute a 7/16" punch in place of the 3/4"?**
A: Depending on what you are punching this may be a mistake.

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.
