From Weber:

"We designed the EG-1 from the ground up, centered around the burrs. Given that burr-centric focus, we offer three different burr sets, providing three different, near-zero retention grind profiles.

The Core (DB-1), which currently ship with all EG-1s; The Ultra (DB-2), built to be the ultimate for pour-over coffee; And The Base (DB-3), our burr set utilized in our original MK1 EG-1s."

This is the DB-2, the 'Ultra Low Fines' burr set which is focussed on delivering a sharper grind distribution with less emphasis on fines.

What does this mean? It means these burrs are skewed towards filter. Grinding for espresso with DB-2 burrs will be difficult, but not impossible.

What grinder does this burr set fit?

It goes without saying that replacing the burr set in your grinder is done so at your own risk, take time and care - follow manufacturer advice for the disassembly of your grinder.
