Eureka Black Diamond 65 mm burrs
The Eureka Black Diamond burrs (65 mm) are a high-end upgrade for selected Eureka coffee grinders. They combine cryogenic treatment, DLC coating and a versatile geometry to deliver consistently precise results from espresso to filter coffee.
Important: These burrs are not universally compatible – please check compatibility carefully.
Who are these burrs for?
- You use a Eureka grinder with 65 mm burrs
- You want more consistent extraction and less readjusting
- You switch between espresso and filter coffee
- You use light to medium roasts
All purpose geometry: a burr for everything
The all purpose variant is the most versatile geometry within the Black Diamond series.
- ✔ Espresso (classic & specialty)
- ✔ Moka
- ✔ Filter coffee
- ✔ Cold brew
Particularly strong for:
- clear, clean flavors
- better separation of flavor notes
- light and medium roasts
Black Diamond technology: what it really delivers
The burrs are treated at extremely low temperatures (cryogenically at -193°C). This permanently changes the metal structure.
- ✔ significantly higher wear resistance
- ✔ consistent grind size over a long time
- ✔ uniform particle distribution
Additionally, a DLC coating (Diamond-Like Carbon) reduces friction and ensures even longer durability.
Result: up to 1,500–1,600 kg of coffee with consistent performance.
⚠️ Compatibility: the most important point
These burrs are only suitable for 65 mm Eureka grinders.
There are two versions:
-
Regular burr (classic, with screws)
-
Blind burr (without screws)
The version must fit your grinder exactly.
Both variants are not interchangeable.
