Review: Makes a perfect hollow-center gasket in one strike--most of the time. - This is one of my favorite tools anymore! I maintain and build brewery equipment and I'm constantly replacing gaskets. As our brewery is located way out in the boonies, buying a gasket means days of waiting for it t get here. But now I just grab ol' Mayhew and a sheet of Viton and hammer away! Perfect concentric gaskets every time. The only time it's a problem is when I need something like 9/16" OD X 7/16" ID (just made a half-dozen of these). Both the 7/16 and 9/16 punches mount on the same shoulder of the mandrel, meaning it takes two operations to make he gasket. But with a little 1/8 or 3/16 punch in the center, it's fairly easy. First, punch out the OD. Remove the larger punch and unscrew the 1/8 center punch about one turn. Put the ID punch on. The 1/8" punch will project just enough to use it to center the ID perfectly. The punches are very sharp and have stayed that way for a year now. I use a plastic cutting board for a substrate and silicone spray on the Viton gasket sheet to make super-clean, square-shouldered gaskets. If you don't lubricate a rubber gasket material, it tends to make a tapered cut. A 1 lb ball-pein hammer does the trick every time, but only if I put the cutting board on the concrete shop floor. My stout workbench isn't stout enough, even with 2X4 rails and 1" plywood top.
Review: Can punch out washers using two dies simultaneously - High quality punch made in France. Two punches can be attached to the handle at same time to punch out washers (which is why I got it). Looks like it will last a lifetime.

### ⭐⭐⭐⭐⭐ Worth every penny
*by G***S on October 28, 2020*

These hole punches are high quality and work flawlessly. The cutting head screws onto the handle by hand and comes off easily so that you can remove the plugs that you cut. I wish that I had known about these punches years ago. The centering feature that lets you cut rings is pretty cool too.
