I don't know if it has been done before, but I managed to put Mazzer Super Jolly burrs into an Eureka E65 grinder.
A week ago I had troubles with my Eureka E65 grinder. No matter what I did, I was not happy with my espresso shots. I opened the machine and the burrs seemed to be a little dull. Should I buy new Eureka burrs? There was also another possibility.
I still had some spare Mazzer Super Jolly burrs. I thought: "Will these burrs fit in my Eureka E65″? The answer is "yes", but it will not be an easy job to get yourself a mixed Eureka and Mazzer grinder.

The picture shows that the Eureka and Mazzer burrs have about the same dimensions. Also the mounting holes are at the same place. There are however also differences. Further inspection shows that the tooth patterns are slightly different. The Mazzer burrs have more and finer teeth. Another difference is the size of the burrs. The Mazzer burrs should have a diameter of 64 mm and the Eureka burrs should have a diameter of 65 mm.
I tried to install the Super Jolly burrs in the Eureka E65. At first everything was fine. The lower burrs carrier welcomed the Mazzer burr without a problem.
The top burr carrier however gave problems. No matter what I tried, the larger diameter of the Super Jolly burr prevented me to properly install the burr. The difference was small, the Super Jolly burr was only 0.2 mm larger. That was strange because the Eureka burrs were supposed to be larger. I asked Tije de Jong if he could help me with a solution. He proposed to use a lathe to make the burr smaller. That was a good idea.

Are Eureka burrs hard to obtain?

No, they are not. I had some spare Mazzer burrs, so I gave it a try. Maybe these burrs will give a better grind quality because of the different tooth patterns. I get the impression that the Mazzer burrs perform better but this needs to be compared with new Eureka burrs to be conclusive.
