Mayhew Tools 66016 Hollow Punch, 36-Piece Set, Black

Hands down the best. You get what you pay for.

These are made of high quality and work very well. They will last for a very long time. Always use a rubber mallet as to not damage the punches.

The price kept me away from buying this set for a long time, but i finally got frustrated enough trying to make leather washers and I seriously regret waiting so long. This is an extremely well made set and it makes perfect concentric circles which is nearly impossible without a set like this. Buy quality - buy one, cry once.

Not long ago I needed a gasket punch. Like I suspect a lot of people do, I bought another brand of punch here on amazon because it was much cheaper and I thought 'all it does is punch gaskets, I dont need anything nice to do the job'. This is bad logic. I bought one of the $40 sets. It arrived with cutting blades that had burrs on the edges. At first I didnt consider this to be a big deal because again 'its just gaskets' but the burrs make it so the gasket doesent seperate cleanly from the stock. The much bigger problem I ran into was how to center the middle hole in the gasket blank. I tried several approaches, from pre punching a center dot in the gasket material, to ink dot indicating center. None of those resulted in properly centered middle holes. If you have to save money, those methods do produce low quality non centered gaskets. I also learned to punch gaskets with a plastic cutting board on a solid surface, not on top of a piece of scrap 2x4 wood. At some point I decided I needed something that produced more repeatable results for the time and effort expended. Then I bought this set. It arrived with nice sharp smooth blades and the center punch is perfectly centered on the exterior punch. "if" you figured out how to accurately center punch with the other style punch, this 2 punches in one shot will outperform in volume production with no comparison. I needed a bunch of gaskets and they needed to be uniform. For me there was no comparison between the two products. I bought both but I am happy with this set.

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.
