Fiorenzato MC F64 Evo Grinder Burrs (Pair) RH 64x37x8.5mm - MP64E001 From  £79.80

Wear these beauties to a Fiorenzato F64E and it will decrease it's grinding time AMAZINGLY!
The grinder has really good consistency as well.
It saved me!
From 9.2seconds it took me to grind 18grams, it went down to 4.2- 4.3 seconds!
4.1 for 17grams my current grinding.
Hope that helped! :)

These burrs grind at twice the speed in my super jolly. Careful adjustment needed so the grinder doesn’t jam up, I’m very happy with the results. Thanks for the great service!
